no_config_form

If the room we requested the configuration from didn't provide a data form.

subject_change_forbidden

If changing the subject of a room is not allowed.

message_error

If this is an unidentified message error.

If we got a presence error the method "presence_error" returns a AnyEvent::XMPP::Error::Presence object with further details. However, this class tries to provide a mapping for you (the developer) to ease the load of figuring out which error means what. To make identification of the errors with XEP-0045 more clear I included the error codes and condition names.

Here are the more descriptive types:

password_required

Entering a room Inform user that a password is required.

(Condition: not-authorized, Code: 401)

banned

Entering a room Inform user that he or she is banned from the room

(Condition: forbidden, Code: 403)

(Condition: item-not-found, Code: 404)

room_not_creatable

Entering a room Inform user that room creation is restricted
