Insufficient tokens for quota 'administrator' and limit 'CLIENT_PROJECT-100s' of service 'pubsub.googleapis.com' for consumer 'project_number:#'

Question

I sometimes get the following error when creating a subscription:

Insufficient tokens for quota \'administrator\' and limit \'CLIENT_PROJECT-100s\' of ser

Answer 1

According to AboulHosen on the GCP Slack:

"It does look like quota is pooled across users of the default application credentials and that the quota is significantly lower for users authenticated in this way. I believe when going to app engine, a service account is created (https://cloud.google.com/appengine/docs/flexible/python/access-control#using_service_accounts), so I would not anticipate this error happening when running on app engine."

So the reason this is happening is because the quota for your admin credentials is being consumed elsewhere, and as far as I know, there is no way to increase this!
