csgdotson opened a new issue #17540:
URL: https://github.com/apache/airflow/issues/17540
Possibly related to installing LDAP authentication, this error appears
almost randomly in the UI in permissions.py when role.permissions are
established. Airflow instance is installed behind a self signed certificate.
Visiting any airflow page may randomly display this error. Refreshing the page
bypasses the error.

**What you expected to happen**:
Render the requested page correctly.
**How to reproduce it**:
Randomly visit any airflow page in the UI.
**Anything else we need to know**:
Appears to be random, but frequently, maybe about every 5 page visits. Could
be session related? Or cache?
