Hey @morgan-dgk, like you mentioned, resolving that intrinsic isn't something currently supported. It is probably a good idea to document which cases are/aren't supported like you mentioned. Let me bring this to the team to see what we can do.

Ok, that seems to have fixed it. Thank you very much for your help.

Just wondering if there are any suggested workarounds for this currently?
In my example, I would like to attach a Lambda Authorizer to a HTTP api using a lambda function defined in the SAM template like so:
LambdaAuthorizerFunc:
Type: AWS::Serverless::Function
Properties:
Handler: src/layers/custom_auth/custom_auth.authorize
Runtime: nodejs20.x
Architectures:
- x86_64
MemorySize: 128
Timeout: 100
API:
Type: AWS::Serverless::HttpApi
Properties:
Auth:
Authorizers:
LambdaAuthorizer:
AuthorizerPayloadFormatVersion: 2.0
FunctionArn:
!GetAtt:
- LambdaAuthorizerFunc
- ARN
Identity:
Headers:
- "context"
However, as !GetAtt does not correctly resolve, this fails.
from aws-sam-cli.

This case should already be supported. Can you try changing the
!GetAtt:
- LambdaAuthorizerFunc
- ARN
to
!GetAtt:
- LambdaAuthorizerFunc
- Arn
from aws-sam-cli.

!GetAtt: - LambdaAuthorizerFunc - ARNto
!GetAtt: - LambdaAuthorizerFunc - Arn
Duh, apologies on my oversight. Debug log still shows this failing after correcting attribute name:
2024-05-01 14:37:15,549 | This Integration URI format is not supported: {'Fn::GetAtt:': ['LambdaAuthorizerFunc', 'Arn']}
2024-05-01 14:37:15,550 | Extracted Function ARN: None
2024-05-01 14:37:15,550 | Unable to parse the Lambda ARN for Authorizer 'LambdaAuthorizer', skipping
from aws-sam-cli.

There also shouldn't be the colon after the !GetAtt (I missed that the first time). So it should be
!GetAtt
- LambdaAuthorizerFunc
- Arn
from aws-sam-cli.
