I haven't downloaded this project but from my experience, this error could occur at two moments

- Trying to synchronize (push) uncommitted objects from your local device db ( > Usually I clean cache/app data to clean local DB and do a clean pull sync from the server (this is not your use case I guess because you are trying to get it running)

- Trying to synchronize file documents (pull) that are referenced by objects which are synced, but are not available on the server. Like a profile image belonging to an account object. If the project contains a data snapshot, this might be the case. Only data is available and not any file documents. > Try to go into Project > Navigation > Native sync profile > Search for a filedocument entity and set download to Nothing.



Alright after i changed set download to “Nothing (preserve data)”, and close & start the Make It Native 8 app and retry again. It  able to run properly.

Much Thanks 👍
