  lifecycle {
    ignore_changes = [labels]
  }
}

Debug Output

I can't post this for privacy reasons, but I can see the API response for the function returns the sourceUploadUrl which should be detected as a change since it originally was sourceArchiveUrl

Expected Behavior

Terraform should detect the drift from sourceArchiveUrl to sourceUploadUrl

Actual Behavior

Changes to source code are not detected

Steps to Reproduce

1. Define a function that uses source_archive_bucket and source_archive_object to specify function source, apply config successfully.
2. Use gcloud app deploy <function name> --source . or otherwise utilize the gcloud source upload functionality
3. Run terraform plan, notice that no changes are detected. You may see that a label has been added but no changes will be detected to the source code.

I've received a similar error when importing a gcloud cli deployed function & trying to change to source_archive_bucket & object

Error while updating cloudfunction configuration: googleapi: Error 400: Invalid value at 'function' (oneof), oneof field 'source_code' is already set. Cannot set 'sourceUploadUrl', invalid
