Path option does not work for prefect-gitlab storage block in a deployment

I am trying to use the prefect-gitlab storage block but defining a path does not appear to work. However building the deployment with the script in the root of the gitlab repository does work. When I define the --path option it fails to find the script, see output below:

Downloading flow code from storage at 'workflows/testflow/'09:20:34 AMprefect.flow_runs
Flow could not be retrieved from deployment.
Traceback (most recent call last):
  File "<frozen importlib._bootstrap_external>", line 844, in exec_module
  File "<frozen importlib._bootstrap_external>", line 980, in get_code
  File "<frozen importlib._bootstrap_external>", line 1037, in get_data
FileNotFoundError: [Errno 2] No such file or directory: '/tmp/tmp30_u8t79prefect/basic_flow.py'

The above exception was the direct cause of the following exception:
