Redundant ignore_changes element: in resource "aws_lambda_function" "this" about terraform-aws-lambda-function HOT 2 OPEN

Looks like this is actually related to hashicorp/terraform-provider-aws#29085

The last_modified value changes on each Terraform run for unknown reasons, which is why most modules that wrap aws_lambda_function ignore that with a lifecycle block.

I tested removing the filename attribute from this module, only leaving s3_key and s3_object (as that's what I need for my use case), and I removed the lifecycle block. The result is that Terraform detected drift on each run for unknown reasons. The last_modified changes every time Terraform runs.

# module.foo.module.lambda_changes.aws_lambda_function.this[0] will be updated in-place
  ~ resource "aws_lambda_function" "this" {
        id                             = "test"
      ~ last_modified                  = "2023-10-05T21:55:22.433+0000" -> (known after apply)
        tags                           = {}
        # (23 unchanged attributes hidden)

        # (2 unchanged blocks hidden)
    }

So, because of the bug I linked above, it's good that this module ignores last_modified. But an unfortunate side-effect of that on modern Terraform versions is the Warning seen in this bug post.

from terraform-aws-lambda-function.

Is there any workaround to get rid of this warning message ?
