i am trying to get started with extension development and when I use gulp extension:fetch it asks for my authid. I thought this would be by netsuite account but when i put that in I get an unexpected error as occurred in my browser and the following url: https://system.netsuite.com/app/login/secure/authorizetoken.nl?oauth_token=undefined what am I supposed to put in for the authid?

do gulp extension:fetch --account <ACCOUNT_NUMBER_HERE>

perfect! thanks
