Assignment Catalog Errors during Item Conversion

Hello,

I have configured some Assignment Catalogs in the system, but during the conversion activity, I encountered an error with some of the values that were already configured:

Error Message: The value of the catalog Assignment Catalog or category **** attribute is not valid for the item assignment.

The error indicates that **** is not part of the Assignment Catalog, but I’ve confirmed that it is configured in the system. This issue is also occurring for two other values.

Could you please advise on what needs to be done to resolve this?

Thank you
