Traceback (most recent call last): File "/usr/local/lib/python2.7/dist-packages/celery/utils/dispatch/signal.py", line 288, in send response = receiver(signal=self, sender=sender, **named) File "/app/redash/worker.py", line 80, in init_celery_flask_app app = safe_create_app() File "/app/redash/__init__.py", line 151, in safe_create_app return create_app() File "/app/redash/__init__.py", line 136, in create_app setup_authentication(app) File "/app/redash/authentication/__init__.py", line 236, in setup_authentication from redash.authentication import google_oauth, saml_auth, remote_user_auth, ldap_auth File "/app/redash/authentication/google_oauth.py", line 4, in <module> from flask_oauthlib.client import OAuth File "/usr/local/lib/python2.7/dist-packages/flask_oauthlib/client.py", line 20, in <module> from .utils import to_bytes File "/usr/local/lib/python2.7/dist-packages/flask_oauthlib/utils.py", line 5, in <module> from oauthlib.common import to_unicode, bytes_type ImportError: cannot import name bytes_type

The deployment works locally on minikube, but this error is reported on GKE.

A summary of the issue and the browser/OS environment in which it occurs.

Steps to Reproduce

1. For builiding the image i first built a base image using dockerfile here

2. I changed the Dockerfile provided in the repository to reference my locally built base image and used that as the final image.

I compared the output of pip freeze on my local _working_ minikube instance vs deployed instance and found version differences in the requests and requests-oauthlib.

Versions in my local copy:

python-dateutil==2.4.2
python-editor==1.0.3
python-geoip==1.2
requests-oauthlib==1.0.0
oauthlib==2.1.0

Versions in GKE:

requests-oauthlib==1.1.0
oauthlib==3.0.0

Technical details:

• Redash Version: 6.0.0 (dev)
• Browser/OS: Chrome (Ubuntu 16.04)
• How did you install Redash: Mentioned above
