I have a ArcGIS online map service running, which I use with a mobile device (Android smartphone) and ESRI Collector in field to acquire archaeological data of a archaeological site in Greece. Due to a bad network on site I use the map service on the mobile device as offline service, synchronizing every evening the daily collected features.
Yesterday I've got an error message during the process of synchronization and the whole process of sychnronization failed. The error message was: Unexpected character (‚c‘ (code 99)) was expecting comma to seperate Array entries.
I'm sure that I do not have any bad entries in my attribute lists and I did not change anything on the map service.
Can somebody help me with this error message?
