I am trying to update a field length of a hosted feature service in ArcGIS Online. I load the update definition page by going to the Admin REST page of the service, and clicking Update Definition:
I then take the JSON and copy/paste it into an editor, like Notepad++.
I find the field I want to update, and change the length. In this case I want the Category field to have a length of 70, rather than 50:
I then copy/paste the JSON back to the Update Definition page and click Update Service Definition, and receive a success message:
But when I go back to the REST page, CATEGORY is still 50 in length:
Not sure what the issue is here. Do I need to set ASync to True?
