Could not save annotations shapes [object Object).

I’m encountering a persistent error in CVAT where annotations fail to save. The UI shows repeated pop-ups saying “Could not save annotations” and lists the shapes as [object Object] instead of meaningful details. This occurs while saving the annotations, and the error appears multiple times in a loop, preventing any progress. The annotations are getting deleted when reloaded in few frames, even the already saved . I’ve attached a screenshot of the error message for reference.
