Error 500: Bad 'foreign' value

[AmanovRu]

When editing case via a minimized form, an Error 500: Bad 'foreign' value comes up when saving. There is no such error when editing via the extended form and saving.

Do you have any manual customizations? Could you attach your custom entityDefs file for Case entity?

[AmanovRu]

I hope I understood correctly and attached the right file

Try to fix your custom relation "audio". Try to specify a "foreign" parameter.

I deleted the audio object completely, the error in the reaped form remains. At the same time, going directly to the extended form, the error is not observed.
