PermissionDenied: 403 error when trying to run async Google Cloud Speech async transcribe - google-cloud-storage

Question

I'm getting the following error when trying to run an async transcription request on a .flac file hosted on google cloud.
$ python3 transcribe_async.py gs://[file].flac
Traceback (most recent call last):
File "[]/anaconda3/lib/python3.6/site-packages/google/api_core/grpc_helpers.py", line 54, in error_remapped_callable
return callable_(*args, **kwargs)

return _end_unary_response_blocking(state, call, False, None)

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

I've added an export statement to my .zshrc file that points to the service account json, I've added myself, the service account email and the project owner and editor as owners of the cloud bucket through the browser, and I ran gcloud auth activate-service-account --key-file="[].json", but nothing helps. What have I forgotten? Any help much appreciated.

You need to make your file publicly readable. Once you set the permissions to allUsers, you will be able to use your file in your request.
