REST API Exports doen not work (dashboard, dataset etc)

[ziggekatten]

Bug description

Any API endpoint for exporting data returns the same error:

"message": "Not a valid rison schema {} is not of type 'array'\n\nFailed validating 'type' in schema:\n {'items': {'type': 'integer'}, 'type': 'array'}\n\nOn instance:\n {}

This happens on 3.1.1, 3.1.2 and 4.0.0 using superset official docker container.

How to reproduce the bug

1. in your browser, goto swagger/v1
2. Authenticate with tokens
3. Klick on any GET endpoint example: api/dataset/export
4. klick try it out
5. klick execute

Checklist

• I have searched Superset docs and Slack and didn't find a solution to my problem.
• I have searched the GitHub issue tracker and didn't find a similar bug report.
• I have checked Superset's logs for errors and if I found a relevant Python stacktrace, I included it here as text in the "additional context" section.
