[Functions] Problem with connecting to MongoDB Atlas

[Alexis LEBLOND]

Hi,

In my Firebase Functions, I need to connect to a MongoDB Atlas Database with mongoose. I saw that the Spark Plan "allows outbound network requests only to Google-owned services".

So I went for the Blake Plan, but I still got an error in the functions logs :

connection error: { MongoError: authentication fail
    at Function.MongoError.create (/user_code/node_modules/mongoose/node_modules/mongodb-core/lib/error.js:31:11)
    at /user_code/node_modules/mongoose/node_modules/mongodb-core/lib/topologies/replset.js:1170:38
    at /user_code/node_modules/mongoose/node_modules/mongodb-core/lib/connection/pool.js:730:7
    at /user_code/node_modules/mongoose/node_modules/mongodb-core/lib/connection/pool.js:706:20
    at finish (/user_code/node_modules/mongoose/node_modules/mongodb-core/lib/auth/scram.js:163:16)
    at handleEnd (/user_code/node_modules/mongoose/node_modules/mongodb-core/lib/auth/scram.js:173:7)
    at Object.cb (/user_code/node_modules/mongoose/node_modules/mongodb-core/lib/auth/scram.js:273:11)
    at Connection.<anonymous> (/user_code/node_modules/mongoose/node_modules/mongodb-core/lib/connection/pool.js:243:32)
    at Connection.g (events.js:291:16)
    at emitTwo (events.js:106:13)
    at Connection.emit (events.js:191:7)
    at TLSSocket.<anonymous> (/user_code/node_modules/mongoose/node_modules/mongodb-core/lib/connection/connection.js:185:10)
    at TLSSocket.g (events.js:291:16)
    at emitNone (events.js:86:13)
    at TLSSocket.emit (events.js:185:7)
    at TLSSocket.Socket._onTimeout (net.js:339:8)
  name: 'MongoError',
  message: 'authentication fail',
  errors: 
   [ { name: 'XXXXX.mongodb.net:27017',
       err: [Object] } ] }

I didn't find any solution to my problem.

By the way, the connection worked on my own NodeJS server, so I can't figure out why it is not working here, maybe it is allowed to requests only Google Services for all Plan ?

Thanks !

Alexis,

That doesn't look like a problem with the outgoing HTTP connection; that looks like an issue with the Mongo auth credentials. I'd start there : )
