解决办法

1. Open the feature service in a new web map with full editing control.

2. Open the attribute table > Table Options > Add Field.

3. Create a new field of the same type and give it a shorter name.

4. Click the gear icon next to the new field > Calculate.

5. Copy the values over to the shorter name field with: Short field name = long field name.

6. Click the gear icon next to the long field name > Delete.
