re-invite outcast user from room - ejabberd

Question

Is there a way via the API to re-invite a user to a room who has previously been outcast?
Created a room
POST /create_room_with_opts
{
"name": "testroompersistent",
"service": "foo",
"host": "bar" ,
"options": {
"title": "Super important meeting",
"description": "This meeting is super important",
"persistent": "true",
"allow_user_invites": "true"
}
}
Invited a user
POST /send_direct_invitation
{
"name": "testroompersistent",
"service": "foo",
"password": "",
"reason": "Check this out!",
"users": "user#companyDomain.co.uk"
}
User joins room
Admin sets user affiliation to "outcast"
POST /set_room_affiliation
{
"name": "testroompersistent",
"service": "foo",
"jid": "userJid",
"affiliation": "outcast"
}
Invited a user again
POST /send_direct_invitation
{
"name": "testroompersistent",
"service": "foo",
"password": "",
"reason": "Check this out!",
"users": "user#companyDomain.co.uk"
}
Set affiliation to "member"
POST /set_room_affiliation
{
"name": "testroompersistent",
"service": "foo",
"jid": "userJid",
"affiliation": "member"
}
I've tried to set the affiliation before and after the invite but to no avail.

Answer 1

I was using the jid I got back from /get_room_occupants to set the affiliation this jid had "/[numbers]" after it and I assume it wasn't setting the affiliation correctly. I was getting 0=success back but it must not have been working correctly.
I have changed the jid to exclude the random numbers I got back from /get_room_occupants. Thanks #badlop for taking the time to respond.
