Hi. I am not sure why, but we started seeing an error for s3 block storage:

Downloading flow code from storage at 'sample'

Flow could not be retrieved from deployment.
Traceback (most recent call last):
  File "<frozen importlib._bootstrap_external>", line 879, in exec_module
  File "<frozen importlib._bootstrap_external>", line 1016, in get_code
  File "<frozen importlib._bootstrap_external>", line 1073, in get_data
FileNotFoundError: [Errno 2] No such file or directory: '/my_org/flows/equities/sample/sample.py'

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

Traceback (most recent call last):

Do you have any ideas what's changed recently?

Check your version of

fsspec

. Pinning fsspec to

2023.1.0

worked for me

You are right, thx
