Managed Entity > Value '00000000' violates facet information 'nullable=false'

Hello,

We have managed entity in RAP where one key field is of type date that can contain default values ('00000000')

When such entity is to be shown in preview the following error is raised>

Value '00000000' violates facet information 'nullable=false'

When we set the filter not to show such entities, no error is raised.

What should we do to accept event entities with date set to default?

Thanks for any hints
