ServiceNow Monitoring Management Pack issues

I am having connectivity issues with the discovery workflow as described at the bottom of this article.

Points towards the ServiceNow account not having the required perms to query the “sys_cluster_state” table.

For testing purposes and I have used my own account which I am a sys admin of servicenow.

To double check I installed postman on the same machine and ran a GET command to this table:


200 for ok and data was returned.

ServiceNow version: Madrid Patch 7

Is this version supported and what else could I have miss read while configuring?
