Specification of 8.2.3. IQ Semantics states:

An entity that receives a stanza of type "result" or "error" MUST NOT respond to the stanza by sending a further IQ response of type "result" or "error"; however, the requesting entity MAY send another request (e.g., an IQ of type "set" to provide obligatory information discovered through a get/result pair).

Created test and fixed the issue.

Andrzej Wójcik (Tigase) commented 3 years ago

This fix forces Tigase XMPP Server to drop all <iq/> of type error or result sent to the user - breaks ie. disco#info, disco#items.

wojciech.kapcia@tigase.net commented 3 years ago

My bad, fixed.
