This API method, or using a Version in the .set JS Helper call
or
window.Twitch.ext.configuration.set('segment', VERSIONMATCHINGBELOW, 'config);
Coupled with the relevant field(s) in the dev console
So the version that was .set needs to match the relevant field entry from the screenshot. Or if EBS calling/setting config you do a second call to Set Extension Required Configuration
if you do not require this system blanking the fields in the dev console should resolve, but you may need to fully uninstall/reinstall the extension after blanking the dev console fields
