Custom Property for ITShop with type date

Hi,

OIM Version 9.2.1

I created an Acc_Product for the IT Shop.  In the table ACC_Param_category the attribute 'IsOldStyle' is false.  For this product i have several CustomParameters of type date.
When i order this product in the it shop and my browser language is Englisch i get a expection and i can't complete the order. In the log of the api server there is the following entry:


[System.Exception] An error occurred while processing the request: PUT http://example.com/ApiServer/portal/cartitem/interactive
[809002] Conversion of 26.02.2025 00:00:00 to Date failed.
[System.FormatException] String was not recognized as a valid DateTime.

When i change my browser language to german, then there is no problem. Is their a fix or setting i don't see?
