Duplicate entry for key

Hi there,

Vikunja API sometimes has the following errors (logged in standard.log):
2021-02-22T17:13:32.443254822+01:00: ERROR :arrow_forward: handler/CreateWeb 10a Error 1062: Duplicate entry ‘25’ for key ‘tasks.PRIMARY’

The user is unable to add new tasks, instead an exception error 500 is displayed. Everything else seems to work fine. After trying to add the task about 100 times it worked, as there was no “duplicate entry” anymore.
I had upgraded vikunja to version v0.16.0 some days ago. I’m running mysql version 8.0.20 on debian 10.

I could imagine the error is based on a bug, where vikunja wants to use primary keys, despite they are already in use for exisiting tasks.

Has anybody had a similar problem?

That sounds like the primary key count got messed up or reset, but I think that’s a MySQL issue and not necessarily something Vikunja could fix.
