Openfire archive list count is always 0 - xmpp

Question

I am using openfire (3.7.1) with monitoring plugin (1.3.0) and am trying to determine if archive is set up correctly. "Archive one-to-one chats" option is selected in archiving settings. In adium xml console I send following xml:
<iq type='get' id='my-1'>
<list xmlns='urn:xmpp:archive' with='user#my-server/resource/'>
<set xmlns='http://jabber.org/protocol/rsm'>
<max>30</max>
</set>
</list>
</iq>
Response I get is:
<iq xmlns='jabber:client' type='result' id='my-1' to='user#my-server/resource'>
<list xmlns='urn:xmpp:archive'>
<set xmlns='http://jabber.org/protocol/rsm'>
<count>0</count>
</set>
</list>
</iq>
But when I check Openfire archive there are a lot conversations for specified user. I don't know how to check if my request or setup is wrong.
UPDATE: Also when I send preferences request, I get 501 error. It is very weird since probably if it was really not implemented, list request should also fail. Am I missing something?
<iq type="get" id="pref1">
<pref xmlns="urn:xmpp:archive"/>
</iq>
<iq type="error" id="pref1" to="user#my-server/resource">
<error type="cancel" code="501">
<feature-not-implemented xmlns="urn:ietf:params:xml:ns:xmpp-stanzas"/>
</error>
</iq>
UPDATE 2:
This is my disco response, where clearly there is archive feature <feature var="urn:xmpp:archive:auto"/>. I don't have any more ideas, what to check next.
<iq from="my-server" type="result" id="info1" to="user#my-server/resource">

Answer 1

I updated monitoring plugin version to 1.3.1-rc1 and it works now. I am quite sure that this was the revert of XmppDateTimeFormat integration specified in changelog:
OF-611 - Monitoring plugin 1.3.0 is not updating IDs of older archived messages.
OF-646 - Reverts XmppDateTimeFormat integration which broke querying via XEP-0136.
OF-664 - Monitoring archive shows null in room chat logs.
