[Debian] Fresh Install fails on MongoDB connection check about ezpaarse

[nojhamster]

Hi there !

I could reproduce this behavior in a VM and figured out the issue. In a fresh Debian install, the DNS has both IPv4 and IPv6 records for localhost, so the Nodejs driver tries to connect using IPv6. However, MongoDB does not listen to IPv6 by default, so the connection fails.

You should be able to fix the issue with one of the following solutions.

Solution 1:
Force ezPAARSE to use IPv4 by creating a config.local.json file and replacing localhost by 127.0.0.1 in the MongoDB URL.

{
  "EZPAARSE_MONGO_URL": "mongodb://127.0.0.1:27017/ezpaarse"
}

Solution 2:
Edit the MongoDB configuration to make it listen to IPv6. In /etc/mongod.conf:

net:
  port: 27017
  bindIp: 127.0.0.1,::1
  ipv6: true

Thanks for this issue.
Could you explicitly check that mongo is started in your Debian 11 install ?
In some distribution you have to manually create the /data/db directory to run

I can't reproduce your problem in my Debian 11/MongoDB 6.0.8 installation

Let us know !

Thanks for the reply.

I can confirm that MongoDB is running, listening to localhost:27017 and I can connect to it with mongosh command :

However I still get the following error :

I'm working on a fresh install on a VM freshly installed out from a Debian NetInst ISO.

Thanks for your help, I can confirm that solves the problem.
I will close this issue and let you decide whether you want to make it appear in your documentation (and where) or not.
