data/aws_lambda_function fails to get container image based lambda

[mousiefasil]

Hi everyone,

I have a project where I am using container images to build Lambdas, in a second project I am want to retrieve them via data aws_lambda_function, but i get a 400 with the error Code signing is not supported for functions created with container images.

I was able narrow the issue down to the data aws_lambda_function part, this issue prevails over mutliple version of terraform so I guess it is a bug in the provider.aws.

Thx in advance.

Recommend using terraform_remote_state via an output on the root module that creates the lambda as a workaround for now (if not a best practice).

I am not sure if calling the terraform_remote_state is best practice. However my current workaround is simple, I just created a variable for the name of the lambda in my second project.

This has been released in version 3.25.0 of the Terraform AWS provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading.
