Error - The issued access token doesn't grant enough permissions.
Why this error occurred
The client may request an access token to access resources beyond a specific
room, like Notifications. In such cases, your auth endpoint should issue an
access token that grants access to multiple rooms using wildcards (*).
1.10 warning
If you saw this warning in your auth endpoint, it's because the version 1.10 allows you to create an access token with no permission, even though it's not recommended. When doing so, Notifications will work with an access token without permissions, and Liveblocks will return all the user's notifications (mentions for example) even if the user doesn't have access to the room. You should move to use wildcards or use ID tokens, and note that this will not be allowed in later versions.
Possible ways to fix it
In your auth endpoint, when the request's property room is undefined, you
should create a token that grants access to multiple rooms. Example:
