QUESTION
the flow I'm expecting:
- on page load, render the silhouette of an image
- enter a guess in the text field or hit the button to show the image from the silhouette
- fetch a new image and re-render the page with the silhouette of the new image
the issue is that the silhouette being rendered is that of the previous image, not the image from the current api response
it is evident when the page loads because the silhouette & picture are blank the first time
the new silhouette is not showing when you hit next because the old silhouette didnt go away
either:
- there is a mistake in the async await logic and syntax
- the DOM div is not getting updated correctly because of the async
- there is some problem with how the image elements are behaving
- there is a problem with the setting and getting HTML objects
- any other problem Im not seeing
what I have tried:
in the code, I have tried setting document.getElementById("sourceImg")
and document.getElementById("silhouetteImg")
directly after async instead of their vars sourceImg
and silhouetteImg
at lines 59 and 69, it didnt seem to change anything
also, I didnt setTimeout
for the last function in the async callback, it didnt make a difference
also, I have tried Auto refresh images in HTML, it didnt make a difference
the api has some incomplete data, just skip all the null responses during testing if you are getting null/broken image
(plain javascript open in a full page)

I need to display different polylines from A to B. So, these lines should be distinguishable from each other. I haved tried to set polylines using pushpoint function with altitude parameter. However it is still on the ground level. And the last polyline I inserted overwrites the previous one. Altitude value works on markers but I want to apply it on polyline. I changed the sample code here markers with altitude as below. You can see the orange line is just on top of the gray line when you change the code with the below one. I would like both lines to be displayed like the markers you see above them.
...ANSWER
Answered 2020-Jan-03 at 16:52Unfortunately, for now only markers support altitudes.
Polylines should follow in near future.
QUESTION
I'm trying to create a Function that is triggered when a message becomes available in an Azure Service Bus subscription. I followed the brief example from the official docs.
Running the app locally via func host start
leads to the following error: "ServiceBusTriggerJS: The binding type 'serviceBusTrigger' is not registered. Please ensure the type is correct and the binding extension is installed."
My setup:
package.json
contains the azure node module: "azure": "^2.2.1-preview"
. Node version is 8.11.
function.json
is as in the example:
ANSWER
Answered 2018-Apr-25 at 05:29You should install the servicebus extension using
func extensions install --package Microsoft.Azure.WebJobs.ServiceBus --version 3.0.0-beta5
.
The extension is used to register the servicebus trigger, making the trigger recognized by your local function run time. It is like a complement for the run time, so it doesn't matter what language you use.
Everything works on my side(js function), feel free to ask if you have further questions.
QUESTION
I'm actually stuck trying to make Microsoft graph API calls inside an Azure Functions (with App Authentication Service enabled). My functions are running with javascript (node).
I can actually get some tokens from the req.headers
(x-ms-token-aad-id-token
, x-ms-token-aad-access-token
, etc.).
I found documentation. The bindings are not working as the function get an HTTP 404
when I try to call it (with the browser), right after I updated and saved the functions.js
file.
I also tried to call manually, using the x-ms-token-aad-id-token
token inside the request headers (Authentication: Bearer xxx-token-xxx
), but get an error response:
"Access token validation failure. Invalid audience."
I tried to use @microsoft/microsoft-graph-client
and got the same message. Maybe it's a configuration problem between my functions and the aad app registration?
ANSWER
Answered 2019-Aug-09 at 13:41There are a couple of issues here:
The URI
https://graph.microsoft.com/me
isn't valid, it lacks a version number in the path. The root URI should behttps://graph.microsoft.com/v1.0
.When authenticating using Client Credentials (i.e. without a user), there is no
/me
. The/me/
segment is an alias for/users/{id of the authenticated user from the token you passed me}
. Since you don't have an "authenticated user",/me
translated to/user/null
which, obviously, doesn't exist (404
).The
x-ms-token-aad-id-token
isn't an Access Token, it's an ID token. Furthermore, it was almost assuredly issued for the resource or scopes you want (invalid audience
). Your function needs to retrieve the token for itself for the tenant you want, using the scopes you require.
You need to explicitly pass in the User Id or User Principal Name (aka UPN):
QUESTION
First of all I am a newbie into Javascript, ES6 etc and I come from Java background. I have a complex javascript array structure (example given below), I am trying to convert this array into a map (similar to how Java has, key value pair kind of thing), key being the permission names (e.g KEY-1, KEY-2, KEY-3, KEY-4,KEY-5 with regards to the javascript array example below) while value being the comma separated values of the actual permission. I can achieve it by looping b thru the nested arrays, but loop is what I am trying to avoid here and wanted to do using map()/reduce()/filter()
Here is an example of how the map should contain the data. Since KEY-2 is present in both the arrays, they will be overridden into one (which is perfectly fine)

QUESTION
I'm attempting to use an output table binding with an Azure Function V2 (node).
I have added the table binding to function.json, as described in the documentation.
...ANSWER
Answered 2019-Feb-23 at 08:53Make sure the parameter has been initialized before usage. The output binding is undefined unless it's initialized or assigned value.
QUESTION
I am attempting to run an Azure Function (JavaScript) locally, but it's failing upon func start
with the following error.
AddConfig: The binding type(s) 'table' are not registered. Please ensure the type is correct and the binding extension is installed.
Please note that I have successfully installed the prerequisites, which at the time or writing were .NET Core 2.1, Node.JS and the Core Tools package.
As is obvious from the error above, I've added an output binding for a Table to function.json for a function called 'AddConfig'. I added the binding as per the documentation.
Is anyone able to advise on what I may be missing here?

Answered 2019-Feb-23 at 08:35func extensions install --package Microsoft.Azure.WebJobs.Extensions.Storage --version 3.0.3

func extensions install
is not useless, the point is that binding type table
is not in the BindingPackageMap hence the extension is not installed. Have open an issue to track.
QUESTION
After using Cognito for a few months, some users in a user pool have now lost the "email_verified" attribute. I can't understand how it is missing or how to recover.
Symptoms are:
- Users can still login
- User password can not change (eg via JS SDK - changePassword), produces error: "x-amzn-errormessage: Cannot reset password for the user as there is no registered/verified email or phone_number"
Getting the user attributes for the user with the list-users CLI shows the attribute is missing
...
ANSWER
Answered 2018-Aug-07 at 04:19I can not find the cause for this problem, other than blaming AWS Cognito.
A workaround/hack/patch is to add the attribute back, this time, the non-mutable check is not a problem
QUESTION
Recently I was using the Sign-up and Sign-in template similar this one developed by Vladimir Budilov.
But now, I've been modifying my application to use the hosted UI developed by Amazon. So my application redirects to the hosted UI, all the authentication is made there and they send me the authentication token, more os less as explained in this tutorial.
Summarizing, I call the hosted UI and do login: https://my_domain/login?response_type=token&client_id=my_client_id&redirect_uri=https://www.example.com
I'm redirected to: https://www.example.com/#id_token=123456789tokens123456789&expires_in=3600&token_type=Bearer
So, I have now the token_id but I can't get the current user or user parameters from this. Could anyone help me with informations or some directions?
I've tried the methods in Amazon developer guide .
It works well when I was using Vladimir Budilov's template but trying to use the token_id, I'm not succeeding. Thanks in advance for your time and help.
...ANSWER
Answered 2018-May-24 at 02:15The attributes you configure to be added as claims are already available inside the id_token with base64 encoding (Since its a JWT token).
You can decode the token and access these attributes both at Client Side using Javascript and on Server.
For more info refer the StackOverflow question How to decode JWT tokens in JavaScript.
Note: If you need to trust these attributes for a backend operation, make sure you verify the JWT signature before trusting the attributes.
QUESTION
I have just started with Amazon Cognito and I want to use it for my web application. I want to develop a stateless app, in which I SignUp/SignIn using Cognito and then using the JWT token in rest of the requests.
I have implemented sign-up and sign-in flow in Node.js using amazon-cognito-identity-js
package and then using the JWT token to call a lambda function using aws-sdk
. Things are as expected till here.
But now the issue is with different user operations like get attribute
, verify attribute
, update password
etc. as listed @
https://docs.aws.amazon.com/cognito/latest/developerguide/using-amazon-cognito-user-identity-pools-javascript-examples.html
All of these operations require cognitoUser
object and in the documentation they are using userPool.getCurrentUser();
expression.
And I have read somewhere that this method returns the last authenticated user. So I think this expression userPool.getCurrentUser();
will cause conflicts. For example if UserB logs in after UserA and UserA tries to update his password, it will not work.
Can someone suggests me what are the possible solutions?
- Should I store the
cognitoUser
object in session at server side ? [This solution breaks my stateless requirement and I will have to maintain session on server side.] - Is there any way to perform these operations using JWT token ?
Please suggest if you can think of any other better approach to implement Cognito in web app.
Thanks.
...ANSWER
Answered 2018-Aug-10 at 23:55We have a stateless app using cognito and lambdas.
The way we have set it up is to not call lambdas directly but to use Api Gateway and lambda-proxy integration.
If you call lambdas directly from your front end code and are using the cognito tokens for authentication then you need to put a lot of logic in each lambda to validate the token, e.g. download the relevant keys, check the signature of the jwt, timestamps, issuer etc. If you use API gateway then you can just create a cognito authorizer and place it in front of your lambdas.
We pass the id_token when making api calls, then the call is validated by the authorizer and the lambda receives all the current attributes set up in the user pool. This means we don't need to make additional calls to get attributes.
For changing the user passwords this can be done from the front-end of the app by calling the cognito api with the access_token if you have allowed it in the user pool client setup.
