I'm trying to import JSON files into MongoDB using `mongoimport`, but I keep getting an authentication error even though I've configured MongoDB to run without auth. **Error:** ``` Failed: (Unauthorized) Command insert requires authentication 2026-03-19T21:11:52.036+0200 0 document(s) imported successfully. 0 document(s) failed to import. ``` **Command:** ```bash mongoimport --host hopper.proxy.rlwy.net:26641 --db edgar --collection app_settings --file app_settings.json ``` **MongoDB Configuration:** * **Image:** mongo:8.0 * **Start Command:**`docker-entrypoint.sh mongod --ipv6 --bind_ip ::,0.0.0.0 --setParameter diagnosticDataCollectionEnabled=false --noauth` * **Auth Variables:** Removed (MONGO\_INITDB\_ROOT\_USERNAME and MONGO\_INITDB\_ROOT\_PASSWORD set to null) * **Volume:** Mounted at /data/db (5000 MB) **What I've tried:** 1.

Removed and recreated the volume **What's happening:** Despite these changes, MongoDB still requires authentication. The deployment appears to complete successfully, but the service still enforces auth. **Question:** Why is MongoDB still requiring authentication even with `--noauth` enabled?

I'm trying to import JSON files into MongoDB using mongoimport, but I keep getting an authentication error even though I've configured MongoDB to run without auth.

Error:

Failed: (Unauthorized) Command insert requires authentication
2026-03-19T21:11:52.036+0200 0 document(s) imported successfully. 0 document(s) failed to import.

Command:

mongoimport --host hopper.proxy.rlwy.net:26641 --db edgar --collection app_settings --file app_settings.json

MongoDB Configuration:

Image: mongo:8.0
Start Command:docker-entrypoint.sh mongod --ipv6 --bind_ip ::,0.0.0.0 --setParameter diagnosticDataCollectionEnabled=false --noauth
Auth Variables: Removed (MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD set to null)
Volume: Mounted at /data/db (5000 MB)

What I've tried:

Added --noauth flag to startCommand
Removed MONGO_INITDB_ROOT_USERNAME and MONGO_INITDB_ROOT_PASSWORD variables
Redeployed MongoDB multiple times
Removed and recreated the volume

What's happening: Despite these changes, MongoDB still requires authentication. The deployment appears to complete successfully, but the service still enforces auth.

Question: Why is MongoDB still requiring authentication even with --noauth enabled? Is there something else I need to configure to disable auth on Railway?

Hello,

your mongodb is still enforcing auth, so just add your credentials to the command:

mongoimport --host hopper.proxy.rlwy.net:26641 --username YOUR_USER --password YOUR_PASS --authenticationDatabase admin --db edgar --collection app_settings --file app_settings.json

check your railway variables tab for the credentials and plug them in; same fix for mongorestore, just add the same three flags

Hope this help you

Welcome!
