Redis Connection Error: ECONNREFUSED at 127.0.0.1:6379 Causing Service Failure

[KazeroG]

Bug Description

When running the application, a connection error occurs with Redis, causing the service to exit. This issue happens because the application cannot connect to 127.0.0.1:6379, resulting in an ECONNREFUSED error in the logs.

ERROR [ExceptionHandler] connect ECONNREFUSED 127.0.0.1:6379
Error: connect ECONNREFUSED 127.0.0.1:6379
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1495:16)

Expected behavior

The application should successfully connect to Redis at 127.0.0.1:6379, or an alternative Redis instance if configured, without raising connection errors. The application should start and run as expected without interruption.

Technical inputs

• The application is configured to connect to Redis on the localhost (127.0.0.1) at port 6379.
• The issue might be fixable by:
• Ensuring Redis is running on the expected address and port.
• Checking firewall settings or Docker container networking if Redis runs in a container.
• Updating environment configurations if Redis is hosted remotely.

Hey @KazeroG - we don't officially maintain the Render.yaml but a pull request would be most welcome! It seems it's missing a redis in Render.yaml https://docs.render.com/redis

[technicalnoodles]

I am having the same issue with the docker compose version from the docs. I have checked that I can connect to the redis service from the host computer. And both containers are in the same docker network

[FelixMalfait]

Yes that's the issue, you're looking at the .env/documentation for main, while the docker version is still the old one :-/.
Ideally one day we should have versioned docs that match the last published version

[technicalnoodles]

Ahhh, alright. So waiting a bit and it should all sync up with the docs

[FelixMalfait]

Yes it should! Sorry

[JTCorrin]

I've got this issue. Not sure from the discussion what the fix is; wait for an update to the docker compose?

[FelixMalfait]

@JTCorrin use the .env.example variable from the latest published version and not the one from the main branch, (so this one https://github.com/twentyhq/twenty/blob/v0.31.3/packages/twenty-server/.env.example)
