interestingly, files are there, so maybe it's a permission issue?

Repro:

pip install tensorflow-transform apache-beam

from apache_beam.ml.transforms.utils import ArtifactsFetcher
artifact_location='gs://temp-storage-for-end-to-end-tests/tft/8825e9c2853143f289c2673feb3bc64b'
artifacts_fetcher = ArtifactsFetcher(artifact_location=artifact_location)
actual_vocab_list = artifacts_fetcher.get_vocab_list()

FileNotFoundError: [Errno 2] No such file or directory: 'gs://temp-storage-for-end-to-end-tests/tft/8825e9c2853143f289c2673feb3bc64b'

Probably failing after #29564.

We should use Beam FileSystem in these cases:

beam/sdks/python/apache_beam/ml/transforms/utils.py

Line 33 in 574e7bf

files = os.listdir(artifact_location)

It might be a regression in the currently cut release.
