Offline Map Sync Failure: Null Pointer

Sean_Perks — Wed, 10 Apr 2024 23:30:31 GMT

Field Maps Version: 24.1.1 build 1059

I have an offline map with two polygons I created on ArcGIS online and configured the form in FieldMaps.

Each polygon contains equivalent fields and both are sync enabled.

The map is downloaded on my iPhone. I create two offline polygons (one each).

One of the polygons sync, the other sync fails with the error: Null Pointer.

I should add, I have had this problem before when it says that sync fails. Usually I can still see the failed features on the online map. This is not the case with this bug, only one polygon will show up on the online map.

I might have just figured it out. I recreated the failed sync polygon and this time I enabled sync from Field Maps Designer instead of AGOL.

The first polygon where sync works was enabled from Field Maps Designer originally and not in the layer settings on AGOL.

I believe for the one that was failing I enabled sync from AGOL after I created it and before I configured the forms in Field Maps Designer.

This was super frustrating so if anyone can explain why this is the case I would be grateful!

I'm having the same problem and have no idea why it is happening.
