Re: core_role_assign_roles to asssign mentor role

So some interesting results, I seem to be able to make the method work for a system role but not for a user level role.  This seems like a new issue since we moved to Moodle 3.7.   Any ideas?

//This worksforeach($parentidlookupas$thisone){// echo "Adding ".$thisone."\n";$role['roleid']=10;//Defines what the parent can access generally. Based on student role$role['userid']=$thisone;$role['contextlevel']="system";$role['contextid']=1;array_push($roles,$role);}unset($resp);try{$resp=$clientm->core_role_assign_roles($roles);}catch(Exception$e){echo$e."\n";}

The above fills $roles with below and works:

array(527) {
  [0]=>
  array(4) {
    ["roleid"]=>
    int(10)
    ["userid"]=>
    int(24844)
    ["contextlevel"]=>
    string(6) "system"
    ["contextid"]=>
    int(1)
  }

//Doesn't flag error but doesn't work either.  Confirmed that the $role parameters are correct by browsing databaseunset($roles);unset($role);unset($resp);$roles=array();foreach($parentstudentas$thiskid){$role['roleid']=9;//A user level role assigning a parent to student.$role['userid']=$parentidlookup[$thiskid['parent']];//Recover Parent's moodle userid$instanceid=$moodlelookup[$thiskid['student']];//Recover Student's moodle userid$thisid=$context_lookup[array_search($instanceid,array_column($context_lookup,1))][0];echo"Found ".$instanceid." with contextid=".$thisid."\n";$role['contextid']=(int)$thisid;$role['instanceid']=(int)$instanceid;$role['contextlevel']='user';array_push($roles,$role);}unset($resp);try{$resp=$clientm->core_role_assign_roles($roles);}catch(Exception$e){echo$e."\n";}var_dump($resp);

The above fills $roles with below and doesn't work. Here userid is parent, instanceid is student and contextid is the context that matches instanceid.

array(534) {
  [0]=>
  array(5) {
    ["roleid"]=>
    int(9)
    ["userid"]=>
    int(37393)
    ["contextid"]=>
    int(36887)
    ["instanceid"]=>
    int(19846)
    ["contextlevel"]=>
    string(4) "user"
  }
