Is März a problem for SeaTable?

I do not yet know if this is a Make.com or SeaTable or neither issue.

We are using SeaTable cloud and make.com SeaTable Rework.

I got a external webhook which sends data to the SeaTable Rework module in Make. The date is 01. Februrar 2025 and is parsed into 01.02.2025. Everything was working fine until saturday, when the first data with März arrived. The module stopped working. Is the “ä” a problem for SeaTable or Make.com?

Could you solve your issue?
