Can't update group permission via REST API

Problem

The Rest API call to update group permissions for a Datameer artifacts fails with the following message:

Group doesn’t exist or isn’t accessible with current permissions

curl -u 'login:password' -X PUT -H 'Content-Type:application/json' -d '{name="<group_name>",flags:{executable:true,readable:true,writale:true}}' 'http://host:port/api/filesystem/files/<ID>/permission/groups/<group_name>'

Cause

The user mixes the usage of PUT and POST methods while setting a new group permission or changing existing ones.

Solution

Use the correct method for desired action.

Change the Group Permission for a File
