Error on submit: 'Unsupported request name'

[JasonJordan00]

This error seems to be pretty sporadic and I've found absolutely no rhyme or reason to it, but this error has been occurring when trying to update an existing point with an attachment and attributes in Field Maps. Restarting the device seems to solve the issue most of the time, but its happened on both Android and iPhone devices for multiple users. I pulled the Field Apps error log and it was blank of any messages however the ArcGIS server log does show this.

I've been seeing this as well. Have you found any further info on it?

Some of my users started getting this too! I am bumping for notifications.

Still don't know what caused it, but I was able to resolve by editing one of the error features from the office. That seemed to get the rest working for that user. Based on that, I think that the error source is on the device itself.
