Hey Kuldeep - You need to set the JWT_SECRET environment variable to a long random string to use the API in production. Without that, an attacker could easily gain access to the system.

Thankyou , I habe set this env and now getting this error

It looks like it's not able to connect to MongoDB. Are you running Mongo in Kubernetes? It seems like the Mongo isn't accessible from your AKS cluster.

yeah i am running mongodb as a pod in same namespace
