[BUG] System.InvalidOperationException: Maximum object size exceeded

[anGie44]

Is there an existing issue for this?

• I have searched the existing issues

Does this issue exist in the latest version?

• I'm using the latest release

Describe the bug?

When running the action in our workflow, we are often seeing the error Error: The template is not valid. System.InvalidOperationException: Maximum object size exceeded

The action is used as follows:
/~https://github.com/hashicorp/terraform-provider-aws/blob/28802c652e04814ed25a7b563bd01bafd875231e/.github/workflows/terraform_provider.yml#L219-L221

To Reproduce

1. Add the step in your github action workflow to run on a repository like the hashicorp/terraform-provider-aws which contains a large collection of files
2. On pull_request triggers, the step can often (not always) fail with the above error

What OS are you seeing the problem on?

ubuntu-latest or ubuntu-20.04

Expected behavior?

The step should succeed with the outputs available in subsequent steps within the workflow.
