Hi Durgesh,

I can't tell what's going on just by looking at the error dump.

Looks like the error is in using the private key which points me to something related with JWT.

Are you using JWT as a server side authentication?

I had a similar situation when I tried to configure JWT access manually as opposed to using the config.json file provided, and it was due to an error in creating the private key file from the config.json (all those \n), so it didn't parsed correctly.

So if you are loading the config.json file and using the java sdk take a look here and here.

Let us know if this helps.
