I'm trying to deploy an application built using nodejs and mongodb. I have mongodb on different VM and I have added the urls for the mongodb servers as a secret in the kubernetes cluster. I have an env variable for the mongodb secret and MONGODB_URL is the var that holds the secret and its declared as process.env.MONGODB_URL in the .js file. But when I try to deploy the app the my pod has a crashloopbackoff status and I get this error when I describe it.

starting container process caused "exec: \"--env=\\\"MONGODB_URL=–n “mongodb://10.128.x.x,10.128.x.x:27017/db?replicaSet=rs0”\\n\\\"\": stat --env=\"MONGODB_URL=–n “mongodb://10.128.x.x,10.128.x.x:27017/db?replicaSet=rs0”\n\": no such file or directory"

this is what my deployment yaml file looks like

       app: s-provider

    readinessProbe:
      httpGet:
        path: /
        port: 3000
    args: ['--env="MONGODB_URL=$(MONGODB_URL)"']
    ports:
    - name: s-provider
      containerPort: 3000

can anyone tell me what the error says and help me to solve it
