Hi, Does anybody know what could be causing theses errors when saving this form to my firebase database. It was saving for a while and then I added more fields to the form and voila, no ability to save.

Kind regards

It is a confirmed BUG in the system. All arrays are broken that are loaded from the Firebase or stored into the Firebase.

The JetAdmin team says they are working on a solution, but can take a while knowing them.

I also have the problem that I can write data in the Firestore anymore since this BUG has been popping up.
