Check Agents status by Agent

We try to use the Agent Management functionality in Pega 7.2.2 by an Agent to check the status of Agents. Running by a user works fine, but when executed by an Agent we got the following error:

2019-10-06 22:42:49,162 [.PRPCWorkManager : 1] (ernal.async.BatchRequestorTask) ERROR - Batch activity "Data-SystemOperations-AgentManagement-AgentInfo.PSCCheckAgentsInNode" threw:

Step 5 contains the following java (as in Agent Mangement):

String nodeId = tools.getParamValue("nodeId");
String agentDetailsInJSONFormat = pega.getSystemOperationsProvider().getAgentManagementAPI().getAllAgentsInfoForNode(nodeId);

try{
tools.getPrimaryPage().adoptJSONArray(agentDetailsInJSONFormat,"pxResults");
}catch(InvalidStreamError e){
oLog.error("error while adopting agents list to clipboard"+e);
e.printStackTrace();
}

Anyone clue why the Agent will not run by an agent?
