Private CLI for 'vserver services name-service ldap check' returns 'Loop detected in next()'

[nainfo]

Hello community

we are getting 'Loop detected in next()' errors when invoking  'vserver services name-service ldap check' via Private CLI

curl -k -X GET "https://XXXXX:443/api/private/cli/vserver/services/name-service/ldap/check?return_timeout=120&return_records=true&vserver=XXXXX&privilege_level=diagno..." -u admin
Enter host password for user 'admin':
{
"records": [
],
"num_records": 0,
"error": {
"message": "Loop detected in next() for table ldap_check. Next on \"XXXXX\" returned \"XXXXX\".",
"code": "262146"
}
}

Same command in CLI works fine

Cluster is running 9.10.1P12

Is this a known issue and fixed in later releases?

Any thoughts on how we might be able to overcome this issue?

thank you
