Error running hook during fetch

[lucianoluzzi]

Hello!
I have tried three or four times running ./cli.sh fetch, but everytime I get the error below:
Hook 'download_from_google_storage --directory --recursive --num_threads=10 --no_auth --quiet --bucket chromium-webrtc-resources src/resources' took 1596.33 secs Error: Command 'vpython src/testing/generate_location_tags.py --out src/testing/location_tags.json' returned non-zero exit status 249 in /webrtc ERRO[7196] error waiting for container: invalid character 'u' looking for beginning of value

Sounds like a Docker issue. A quick search shows correlation with docker/for-mac#5139
