Fetch Attendance created with API v1 using API v2

Hello,

I encountered some errors trying to use the attendance-periods API v2.

Is it not possible to query an attendance that was created using the v1 API with the v2 API?

The request ends in the following error:

title: Internal Server Error
detail: The request cannot be completed due to internal server error

I assume there is some sort of breaking change between the data models of v1 and v2. If this is the case, is there a way to migrate the attendances to v2?

Many thanks in advance.
