External CalDav integration

Configuration
1

Hello @bertrandda!

I’m testing the external CalDav integration that will replace the original one and I’m having an issue.

I’m using Google Calendar. After adding my main account (I went back to check the original integration to get the address and it would be interesting if it were offered in a list for example), an error appears. It says that 6 calendars have been synchronized but one is in error.

I discovered that the one causing the problem is the one from my main account. In the logs, you can see this:

Any ideas?
