QUESTION
I need a cloud function that triggers automatically once per day and query in my "users" collection where "watched" field is true and update all of them as false. I get "13:26 error Parsing error: Unexpected token MyFirstRef" this error in my terminal while deploying my function. I am not familiar with js so can anyone please correct function. Thanks.
...ANSWER
Answered 2021-Jun-15 at 16:13There are several points to correct in your code:
- You need to return a Promise when all the asynchronous job is completed. See this doc for more details.
- If you use the
awaitkeyword, you need to declare the functionasync, see here. - A
QuerySnapshothas aforEach()method - You can get the
DocumentReferenceof a doc from theQuerySnapshotjust by using therefproperty.
The following should therefore do the trick:

...ANSWER
Answered 2021-Jun-13 at 10:10Don't ever use any when writing in TypeScript as you essentially "switch off" TypeScript and lose valuable type information such as why your code isn't working.
If you use the following lines, the type of change (which should be snapshot) and context are automatically set as QueryDocumentSnapshot and EventContext respectively as defined by the onDelete method.

QUESTION
I am having problems when implementing a translator in dialogflow, I don't know what will be wrong, the code does not work for me. could you please guide me. I clarify that the line editor does not let me implement an asynchronous function.
...ANSWER
Answered 2021-Jun-06 at 10:08There are some issues with the code. The code needs to require the needed libraries, to define agent, to include an intent map, and the function must be named dialogflowFirebaseFulfillment to use the Dialogflow fulfillment library.
You can see the Dialogflow fulfillment library docs and samples to see the required boilerplate elements 1 then add your code around them.
QUESTION
Ive been trying unsuccessfully to get an http request to the Genius API server running through my cloud functions node.js instance. I am currently stuck getting this 'Server Error' message and am not sure how else to move around this. I am new to http requests, so was wondering if there were any glaring mistakes im making in this request? Or possible ideas for how to get more useful information from the error console
My console log currently outputs: (node:43068) UnhandledPromiseRejectionWarning: Error: Server error.
...
ANSWER
Answered 2021-Jun-05 at 15:40In your then handler you are throwing exceptions that are not catched anywhere (at least not in the code you are showing us). Thus, you get an UnhandledPromiseRejectionWarning. And as this is all inside an express routehandler, you are not returning anything to your client calling this route (not even if the authenication call is successful)
QUESTION
I'm trying to implement a Firebase function that generates a custom token for my app. But I keep getting the following error message :
Error: could not handle the request
Or it ends up in timeout.
Do you have any idea of what could be wrong with my code hereafter ? I'm trying it with a 'test' uid.
...ANSWER
Answered 2021-Jun-05 at 12:47Your Cloud Function is an HTTPS one. In order to terminate it you need to call res.redirect(), res.send(), or res.end() as explained in the doc.
In your code you actually return the Promises chain: this is the correct way to terminate Cloud function triggered by background events (which is not the case of an HTTPS Cloud Function which is triggered by a call to the URL it exposes).
So, the following changes should do the trick (untested):
QUESTION
My firebase functions was running fine till last night, but it has stopped working now. When I run my functions I get this error on my Google cloud platform log -
"Step #5 - "exporter": [31;1mERROR: [0mfailed to export: failed to write image to the following tags: [us.gcr.io/tookforms/gcf/us-central1/77926137-2972-4613-947e-c66d12cfd46f:calc_version-59: GET https://storage.googleapis.com/us.artifacts.tookforms.appspot.com/containers/images/sha256:b18e538d0dbca11a254142f571dfce8058959925b5e8c2c25679211b8b1bf0c6?access_token=REDACTED: unexpected status code 404 Not Found: NoSuchKeyThe specified key does not exist.

It's saying that it's trying to upload some image to somewhere on google cloud platform. But I don't have anything to do with any image in my function. I don't even understand exactly what the "image" means over here.
This is the second error I am getting just below the first error -
ERROR: build step 5 "us.gcr.io/fn-img/buildpacks/nodejs12/builder:nodejs12_20210310_12_21_0_RC00" failed: step exited with non-zero status: 246

I am trying to construct an API end point to receive small Audio files from the user and upload it to firebase storage. I am using multer to handle the form data but when testing with postman i'm not sure if upload.single('file') is working since req.body and req.file is undefined. am I doing something wrong?
I read a lot of stackoverflow threads about this but non of them worked

Answered 2021-Jun-04 at 06:50Turns out Firebase and multer don't go well together. I referred to this article which explains why multer does not work and how to achieve the same goal with Busboy.

Take the example below:
...ANSWER
Answered 2021-Jun-03 at 15:31Each exported function runs in its own container(s), which are built/rebuilt when you deploy that function. So if you run firebase deploy --only functions:functionOne, only functionOne will run with the updated dependency. The container of functionTwo will be unmodified, and run with its old dependency version.
QUESTION
I'm trying to send data to my Nodejs server (hosted on Firebase), from Reactjs to retrieve data from an API call.
It worked when the API url was hard coded, so the issue should be in sending the data from React to Node. I'm currently trying to have it only return one request, but once I'm able to do that, I will be trying to fetch multiple requests.
The result is to populate the stocks state with the response.
My React code looks like this:
...ANSWER
Answered 2021-May-31 at 12:56In order to get the data from the frontend you will need to make a post endpoint instead in your Node server and send a GET request inside that method.
