Hi guys!
I’m facing an error when trying to connect to a mongodb database that only happens inside an AWS Lambda. The same code being executed by a spike in my environment, using the same nodejs dependency versions, returns the expected result and creates a connection with mongodb without the slightest problem.
Another very similar connection code also works in Fargate containers on AWS ECS.
I’ve taken care of the network configuration, I’ve enabled public access. I no longer know what it could be.
Driver version: “mongodb”: “^6.3.0”
Connection string: “mongodb+srv://user:password@myapp-staging.ufqgvmg.mongodb.net/?retryWrites=true&w=majority” (I’ve changed some parameters, just to be on the safe side)
My code:
class MongoDbClientStore {
constructor(args: IMongoDbClientStoreArgs) {
this.driver = new MongoClient(args.connectionUri)
this.database = args.database
this.collection = args.collection
}
private readonly database: string
private readonly collection: string
private readonly driver: MongoClient
async init() {
try {
await this.driver.connect() // fail here.
await this.driver.db("admin").command({ ping: 1 });
console.log('MongoDB connection successfully stabilized')
} catch (err) {
console.error('MongoDB connection failed: ', err)
}
}
Error returned:
ERROR MongoDB connection failed: MongoRuntimeError: Unable to parse ac-sgtcjuj-shard-00-00.ufqgvmg.mongodb.net:27017 with URL

Thank you very much for all your help!
