Hi! PubSub server returns an "Invalid access token" error when I'm trying to subscribe to db updates.
I successfully use exactly that same token to query your rest api.
My guess is that here:
https://github.com/OpenframeProject/Openframe-PubSubServer/blob/master/server-auth.js#L13
either api path or env.API_EXPOSED_URL is missing "/v0" segment.
Of course, it can be any other network issue too.
