How can i fix this error? There is another method to add feature to layer on Wep App?
I attached screen shots, may be can help.
I also experienced this error in the developer console after updating my web map, but then it went back to working normally again after I updated my SmartEditor widget settings. Might have been something related to which layers and fields were editable, I'm not totally sure.
I'm sorry, this fix should be made available in Enterprise 10.9, but won't be available in previous versions of Enterprise. If you need this fix earlier, you can try adding the current version of the Smart Editor widget as a custom widget to your Portal: Add custom widgets—Portal for ArcGIS | Documentation for ArcGIS Enterprise.
