QUESTION
I have a lambda trigger in my user pool (post confirmation lambda trigger), which calls the code below:
...ANSWER
Answered 2022-Apr-16 at 03:47I have found the answer. As isavinof said, the value has a string type, which wasn't working initially, however, it turned out to be a permissions error ( AccessDeniedException ).
To fix the problem, I followed this answer: https://stackoverflow.com/a/67678111/1898662
I. CREATING THE POLICY (FOR PERMISSION)
- Go to IAM console -> Policies -> Create Policy.
- Choose "Cognito User Pools" Services.
- Specify the desired actions for which you need permission for (List, Read,
etc.) In this case, it was write -> AdminUpdateUserAttributesInput - Specify Resources - the userpool region and id
- Choose request conditions (optional).
- Add Tags (Optional) - helps with searching in a large list of policies
- Give name and description of the policy - be exact as it helps to ensure you have chosen the right one in the next stage
- Click on "Create Policy" button. POLICY CREATED.
II. ADDING THE POLICY TO THE USER :
- Go to IAM console -> Users (in this case, roles, not users, and find the lambda function role. If you don't know it, view it in the lambda backend, under permissions)
- Select the desired role.
- In permissions tab, click on Add Permissions.
- Click on "Attach existing policy directly".
- Search for the policy you just created.
- Click on "Add Permissions" ISSUE IS RESOLVED.
QUESTION
I'm performing a simple table Scan to get all items from my DynamoDB table, products
. Here is the whole Lambda:
ANSWER
Answered 2022-Apr-03 at 18:40Scanning the table returns the map of items and you want to convert map into the struct so in order to convert the list of maps to the struct you want to use attributevalue.UnmarshalListOfMaps under aws-sdk-go-v2. In the previous version it was in the dynamodbattribute but they decided to change the package in the v2.
QUESTION
I know there are no folders in Amazon S3, but we can emulate them by using "/" on the key name. Given that, is it possible using the AWS SDK for Go v2 to calculate the size of a folder? Or do I have to retrieve all objects in the folder and then calculate one by one the size?
...ANSWER
Answered 2021-Sep-19 at 09:09Not sure if the easiest way, however you can iterate over your objects list of interest - https://docs.aws.amazon.com/AmazonS3/latest/API/API_ListObjectsV2.html, and aggregate the size locally.

QUESTION
In aws-sdk-v2 library for Go, we have the following interfaces definitions:
...ANSWER
Answered 2022-Feb-28 at 09:08Likely you are using an old version of Go. Overlapping method sets are allowed since Go 1.14, and the code compiles on the Go Playground.
Quoting from Go 1.14 release log:
Per the overlapping interfaces proposal, Go 1.14 now permits embedding of interfaces with overlapping method sets: methods from an embedded interface may have the same names and identical signatures as methods already present in the (embedding) interface. This solves problems that typically (but not exclusively) occur with diamond-shaped embedding graphs. Explicitly declared methods in an interface must remain unique, as before.
If you get a compile-time error for the code you posted, that suggests you're using a Go prior to 1.14. Urgently update! Please note that only the last 2 major versions are supported (currently 1.17 and 1.16). You using a version like 1.13 is a major risk!
QUESTION
I acquired the oauth2 token using the usual workflow via golang.org/x/oauth2 but can't authenticate graph sdk (github.com/microsoftgraph/msgraph-sdk-go). My app allows both multi-tenant AD and personal accounts.
I implemented azcore.TokenCredential
interface:
ANSWER
Answered 2022-Feb-23 at 08:45Fixed by changing the scope in the oauth2 config to https://graph.microsoft.com/.default
. Now when a user signs in it sees a consent screen. I also added necessary Microsoft Graph permissions from the API permissions screen of my App Registration page.
QUESTION
I have a Go service that needs to connect Keyspaces on AWS. My pod has a role and AWS_SECRET_ACCESS_KEY
, AWS_ACCESS_KEY_ID
and AWS_SESSION_TOKEN
env vars.
I want to use aws SDK v2. What credential provider should I use? ec2rolecreds
or other one (maybe stscreds
)?
I tried to implement example from here. But I get an error
...ANSWER
Answered 2022-Feb-08 at 00:26no EC2 IMDS role found, operation error ec2imds: GetMetadata, exceeded maximum number of attempts, 3, request send failed, Get \"http://169.254.169.254/latest/meta-data/iam/security-credentials/\": dial tcp 169.254.169.254:80: connect: host is down
Your snippet of code is attempting to use the EC2 instance meta-data service to read an IAM role to use. For that to work, you need to be able to communicate with it, and the role must be attached to the instance.
Is your Go service running on an EC2 instance? If not, that would explain your error. If it is, make sure the process or container has appropriate network access (eg: network namespace) to communicate with 169.254.169.254.
