I keep getting this error when adding features.
I have two feature layers, and I am adding and updating features on them from an iOS app.
When I call add/update/deleteFeatures and check the didFailFeatureEditsWithError, the error is:
Illegal Start of Token.
The interesting thing is that some requests to update work, and some fail. In the controller I am calling 3-4 updates.
Any ideas what this means?
