Error while accessing the export API after Update on 3.0.3

1

Hello,

When calling the Export HTTP API such as https://indico.desy.de/export/event/28139.ics
I get the following errors (indico.log) after updating to 3.0.3 this morning:

2021-12-16 11:26:19,583  ERROR    5c3c9de76957471d  -       indico.flask              '>' not supported between instances of 'NoneType' and 'int'
Traceback (most recent call last):
  File "/opt/indico/.venv/lib/python3.9/site-packages/flask/app.py", line 1513, in full_dispatch_request
    rv = self.dispatch_request()
  File "/opt/indico/.venv/lib/python3.9/site-packages/flask/app.py", line 1499, in dispatch_request
    return self.ensure_sync(self.view_functions[rule.endpoint])(**req.view_args)

    if ttl > 0:
TypeError: '>' not supported between instances of 'NoneType' and 'int'

Does anyone have an idea what I could have done wrong during the update, on all other computers on which I have made the update, there is no error.

Thanks in advance and best regards
Marcus

try saving the http api settings in the admin area to explicit set the api cache ttl to 0 - looks like it’s None on your instance

Thanks a lot and again learned something about Indico.
