Unable to Submit - Java Error

[JosephHilliard94]

Hi there,

One of my users is having this message when capturing a linear feature in ArcGIS Field Maps:

'Unable to Submit - Attempt to invoke interface method ‘java.lang.Objectjava.util.Map$Entry.getKey()’ on a null object reference' - any ideas?

Thanks!

Joe
