# appError

Emitted when something unexpected or not allowed happens in the room.

#### Here is a list of the possible error names:

* `permissions-rejected` -> emitted when user tries to screen share, but browser doesn't have enough permissions for it
* `not-allowed` -> emitted when a not allowed action was requested by the user. For example if a user tries to start a recording and recording is not supported in the room, he will receive a `not-allowed` type.
* `forbidden-action` -> emitted when a forbidden action was requested by the user. For example if a user tries to end a session and doesn't have a permission to do so, then the `forbidden-action` type.
