Dont allow Conditions for fields that are not filterable
For example with History objects from Salesforce not all fields are filterable, specifically the OldValue and NewValue fields. Despite not being filterable as stated by Salesforce, you can add a condition for these fields on the Model and they will then be ignored as they are not filterable. The fields should not be listed as on option for conditions.
It is important to note that these fields can be filtered for in Reports https://help.salesforce.com/s/articleView?id=sf.reports_filter_old_value_new_value.htm&type=5
What is additionally confusing about this issue is that, while Salesforce doesn't list "Filterable" as a property of the Old Value or New Value fields in the api documentation linked above, they are filterable in reports as described here in their docs.
