dashboard export not working with latest 1.4.1

[pavlozt]

Something strange with versions and images in dockerhub.

How to reproduce the bug

git checkout 1.4.1
TAG=1.4.1 docker-compose -f docker-compose-non-dev.yml up -d
docker exec superset_app superset export_dashboards

Actual results

Environment

• superset version: 1.4.1

Checklist

• I have checked the superset logs for python stacktraces and included it here as text if there are any.
• I have reproduced the issue with at least the latest released version of superset.
• I have checked the issue tracker for the same issue and I haven't found one similar.

Additional context

Problem is easy to get around by adding "requests==2.26.0" to to the file docker/requirements-local.txt
What would break down could not be found.

Pinging @hughhhh sine he knows his way around this pretty well. I don't see this error happening in the current master branch here. If this is no longer an issue, let's close it. Or if we need to add that dependency as suggested above, @hughhhh, that works too!

requests is currently required and I am able to export a dashboard in Superset version 3.0.0. Given that, and the age of this issue, I'm going to close it.
