You must be the owner of the application

Well... I am

I'm running the command from npm scripts

WEEBLY_SECRET=my_secret WEEBLY_CLIENT_ID=my_id weeblybundle app .tmp/client/public

Do I need any specific permissions or something?

It appears that there is a WEEBLY_DOMAIN that must be set in order for this to operate, but when set, the operation is FORBIDDEN (403).
