Syncing Error

[Suhaibb]

Hello everyone,

I hope that all of you are doing well, I have a problem with my app when I am trying to sync after doing the necessary modifications, I get an error message (Reference object not set to an instance of an object), but when I have deleted the attachments, the sync has done successfully, I need the solution, please.

Normally this error means there is something wrong with the code and I would propose to contact support > devs with this.
