Connecting to MongoDB - Command 'createIndexes' requires authentication (Maybe Agenda.js related?) - node.js

Question

As I'm introducing authentication for my MongoDB instance in Docker, I ran into problems which are probably related to the way agenda.js tries to connect to MongoDB, as the connection string invokes successful logs for mongoose connecting to the DB, therefore I assume the string should be valid.
Everything worked until I changed the connection string to use authentication. I verified the users are properly created in the database and also tried variations of the connection string and deleting/installing node modules.
Following output I get upon running docker-compose up:

How I initialize agenda:
class mScheduler {
constructor() {
if(typeof mScheduler.instance === 'object')
return mScheduler.instance;
this.agenda = new Agenda({ db: {address: config.connectionString, collection: 'agendaJobs', options: { useNewUrlParser: true }}, processEvery: '2 seconds', maxConcurrency : MAX_CONC});
process.on('SIGTERM', this.endJobs);
process.on('SIGINT', this.endJobs);
setImmediate(async ()=> await this.agenda.start());
mScheduler.instance = this;
return this;
}
someOtherMethods()
}
module.exports = new mScheduler();

Answer 1

try this
workaround these deprecation warnings with Mongoose provided options
const connectionOptions = {
useNewUrlParser: true,
useCreateIndex: true,
useFindAndModify: false,
useUnifiedTopology: true,
autoIndex: false
};
this.agenda = new Agenda({ db: {address: config.connectionString, collection: 'agendaJobs', options: connectionOptions}, processEvery: '2 seconds', maxConcurrency : MAX_CONC});
