SYNC999: Sync unexpected
What this means
Syncing hit an unexpected problem.
Check the action named in this entry finished; if it didn't, repeat it. If this repeats, tap Copy debug info and send it to support.
Your data
Don't clear this device's data — it may hold changes your store doesn't have yet. If the action named in the entry didn't finish, repeat it.
Troubleshoot
- Expand the log entry and find the action it names. Check it finished — for a save, open the order or record and check the change shows up. If it did, WCPOS sends it by itself, so leave it.
- If it didn't finish, repeat it. If the log entry says the change was never saved on this device, nothing was captured.
- Note the code and any reason on the log entry: a 999 code means the specific cause has no dedicated code yet, so this context is exactly what support needs.
- If this repeats, tap Copy debug info on the Logs tab and send it to support — reporting it is how the specific code gets added.
