[GitHub] [airflow] csgdotson opened a new issue #17540: Airflow 2.1.2 AttributeError: 'NoneType' object has no attribute 'name'
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.
**Apache Airflow version**:
2.1.2
**Apache Airflow Provider versions** (please include all providers that are relevant to your bug):
apache-airflow-providers-celery==2.0.0
apache-airflow-providers-elasticsearch==2.0.2
apache-airflow-providers-ftp==2.0.0
apache-airflow-providers-http==2.0.0
apache-airflow-providers-imap==2.0.0
apache-airflow-providers-postgres==2.0.0
apache-airflow-providers-sqlite==2.0.0
**Environment**:
RHEL 7.9 on vmware
**What happened**:
Browse random Airflow UI pages and this is the result:
Ooops!
Something bad has happened.
Please consider letting us know by creating a bug report using GitHub.
Python version: 3.6.8
Airflow version: 2.1.2

**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?

Can this DB error from the log be related?
```
Aug 9 03:29:53 airflow-webserver: [SQL: INSERT INTO ab_permission (id, name) VALUES (nextval('ab_permission_id_seq'), %(name)s) RETURNING ab_permission.id]

Aug 9 03:29:53 airflow-webserver: (Background on this error at: http://sqlalche.me/e/13/f405)
```
If so, and this is simply a database permission issue, I don't understand how this error isn't consistently generated.

Yes, this is resolved, not a bug. The issue was a bad permission group on the ab_permission table.
