Unable to connect to database: ReplicaSetNoPrimary Error


I received the above error after trying to connect to my mongo cluster via nodejs.

Here is my uri string with credentials omitted:
mongodb://username:password@shard.mongodb.net:27017,shard.mongodb.net:27017,shard.mongodb.net:27017/admin?ssl=true&replicaSet=atlas-shard0&readPreference=primary&connectTimeoutMS=10000&authSource=admin&authMechanism=SCRAM-SHA-1

I also tested this when whitelisting all IP addresses and still getting the error. What am i doing wrong here?

@Stennie can you please help on this issue?

@Stennie @Piti.Champeethong can you help on this… i’m working on mongoose with lambda function it would work first time but after sometime would get this error?

Welcome to the MongoDB Community @santhosh_h1 !

Please share more details about your environment:

  • version of Mongoose
  • version of MongoDB Node.js driver
  • description of how your issue manifests

You may find this tutorial a helpful reference: Write A Serverless Function with AWS Lambda and MongoDB | MongoDB

If your Lambda function works for a while and eventually runs into a connection error, I think this suggests you may have cached a stale connection and perhaps need some retry logic.

Stennie
