Loopback MongoError: not authorized for query on heroku
I'm using Loopback for my server with the following setup:
"loopback": "^2.36.0",
"loopback-boot": "^2.23.0",
"loopback-component-explorer": "^2.4.0",
"loopback-component-storage": "^1.9.1",
"loopback-connector-mongodb": "^1.17.0",
"loopback-datasource-juggler": "^2.53.0",
It's connecting to a mongoDB that's on mlab.com
My main query includes a model and it's dependencies, ex:
GET /api/course/1234
PARAMS filter = {
include: [
{relation:'students'},
{relation:'documents'},
{relation:'modules'}
]
}
99.9% of the time, it works perfectly. But when I start having more activity on the platform, I start getting this error before the server starts crashing. Here's the error:
MongoError: not authorized for query on db.student
at Function.MongoError.create (/app/node_modules/mongodb-core/lib/error.js:31:11)
at queryCallback (/app/node_modules/mongodb-core/lib/cursor.js:182:34)

at Socket.<anonymous> (/app/node_modules/mongodb-core/lib/connection/connection.js:302:22)
Sometimes it's on db.students , sometimes it's on db.documents ... seems random and I have no idea how to fix it.
To connect to the DB, I use the URI provided by mlab. Which looks like this:
mongodb://<dbuser>:<dbpassword>@<dbpath>/<dbname>
With and without ?&authMode=scram-sha1&rm.tcpNoDelay=true , but still getting errors with.
Any ideas what's happening and how to fix this?
__ Edit: I've tried a couple of different versions with no luck. Latest is:
"loopback": "^2.22.0",
"loopback-boot": "^2.6.5",
"loopback-component-explorer": "^2.4.0",
"loopback-component-storage": "^1.9.1",
"loopback-connector-mongodb": "^1.17.0",
"loopback-datasource-juggler": "^2.39.0",
__ Edit: I found this post on Github: https://github.com/strongloop/loopback-connector-mongodb/issues/251 which seems to be the same error, I followed what the others said solved their problems by changing the mongodb@2.1.18 but still no luck...
The solution was to update Loopback to the latest version. The Loopback library includes the MongoDB Node driver as a dependency and uses the driver to connect to a MongoDB database.
Previous versions of the MongoDB Node driver have known connection/authentication issues. By updating to the latest Loopback version, a more recent version of the Node driver was installed.
