Enabling the Allow Other option in the Survey123 Web Application for a multiple choice question causes Offline Packaging to fail when using the Survey123 hosted feature layer in a Web Map (when the field characters come out to greater than 30)
Duplicate of BUG-000143613: This is not a Survey123 issue and is a known limitation where ArcGIS Field Maps cannot download services for offline use if a field name is greater than 31 characters.
解决办法
First workaround:
Click Modify Schema when trying to publish, and rename the field for the Other option and then publish.
Second Workaround:
Disable the Allow Other option, click Save, and republish.
Go to the Feature Layer Item Details Page and remove the field that was created from the Allow Other (must be Other - Field Name) by clicking the Field and deleting it.
Create a new web map with this edited feature layer and package an offline area.
