Unable to receive affiliation change notification from iq - erlang

Question

I am using mod muc_light in MongooseIM from source code(ver-3.1.0) and taking help from this article I am able to perform the below operations successfully without any trouble:
create a new muc light room.
send/receive text message stanza
queries MAM and receives regular groupchat message. ['6.2.1 Groupchat message from occupant' from above article][Even, here I am getting the muc info but since this is related to a particular muc light room. So, not much useful.]
But I am unable to query MAM and receives an affiliation change notification. See topic [6.2.2 Affiliation change] in the above article link.
Following is the request/response for 'affiliation change notification'
// Request to server with type='set'
<iq type='set'
id='mamget2'
to='muclight.localhost'>
<query xmlns='urn:xmpp:mam:1' queryid='f37'/>
</iq>

<iq xmlns='jabber:client'

</error>
</iq>
MongooseIM config:
{mod_muc_light, [
{host, "muclight.#HOST#"},
{backend, rdbms},
{max_occupants, 256}
]},
{mod_mam_meta, [
{backend, rdbms},
{no_stanzaid_element, true},
{is_archivable_message, "muclight.#HOST#"},
{pm, false},
{muc, [
{host, "muclight.#HOST#"}
]}
]}
Questions/concerns:
Am I doing something wrong in config? - [I doubt this, because some others operation are working fine like mentioned above]
Am I sending the incorrect IQ stanza - [I doubt this because I am copying the exact same stanza example provided in above link]
Should I update MongooseIM. [May be]
Anything else?
Please help
