Debug Output

│ Error: error creating run for workspace ws-7xTk3aNBB......: unprocessable entity
│ 
│ Configuration version is missing

Expected Behavior

The destroy workspace run should execute successfully and must not fail even when the workspace contains no resources.
Use case:

1. We create a workspace along with a tfe_workspace_run and several other resources.
2. Terraform code that uses this workspace is applied from a separate CI/CD pipeline.
3. In some edge cases (unhappy paths), the apply step in (2) fails, leaving the workspace empty (no Terraform resources in the state).
4. As part of the workspace lifecycle, we then remove the workspace created in (1). This triggers a destroy run, as expected. However, the destroy run fails with the error Configuration version is missing.
   While this behavior is technically expected when no resources exist, there should be an option to suppress this error and allow the destroy run to succeed.

Actual Behavior

destroy run of tfe_workspace_run fails with Configuration version is missing.
