Are you using subscription? If so ask directly of the Bonitasoft Support desk, you’re allowed to do this with subscription. Otherwise unlikely many will have this experience in Community. regards Seán _PS: While I understand this may not be the answer you are looking for it does answer your question, please mark as resolved by ticking the tick mark on the left of this reply so others now it is closed._ ---

Error is same but this is not the problem. There were no changes done in any configuration file. ---

Yes … I’m using subscription. I have raised this Bonita Support too. I was hoping for a quick reply so posted the issue here.
