Intermittent Terraform Cloud Connection Failures in GitHub Actions

[KentonParton]

Expected Behavior

When running pnpm exec cdktf deploy stack-name --auto-approve within GitHub Actions, the workflow should complete successfully with a proper JSON response from Terraform Cloud after the apply operation completes.

Actual Behavior

While the actual Terraform apply operation completes successfully (resources are correctly created/modified/destroyed), the connection to Terraform Cloud sometimes drops during the final output phase. This results in a JSON parsing error and causes the GitHub Actions workflow to fail with exit code 201. Error message:

     Apply complete! Resources: 1 added, 0 changed, 1 destroyed.

task: Failed to run task "deploy:terraform-shared": exit status 1
Error: Process completed with exit code 201.

Steps to Reproduce

Unfortunately, the issue is intermittent. I have not been able to reproduce consistently
