Unable to send the output via e-mail when UBE is submitted and gets completed

Dear Team,

When a report gets submitted on server, it calls B98ORCH(CallOrchestrationNotification) and once report gets completed, its unable to send the output to users.

Please find the error log. May i know what is table name where aisSessionint checks the end point? How to troubleshoot it?

Curl command is working for my id but not JDE. What could be issue?

curl -i -X POST -H "Content-Type:application/json" https://AIS:PORT/jderest/v2/tokenrequest -d "{\"username\":\"USERID\", \"password\": \"*********\"}"

Error in ENT log:

aisSessionInit: ALERT: unable to find endpoint in tables for user XXXX, env JPD920, falling back to JDE.INI settings.
