Solved Cannot start NodebB: "Cannot find module ./undefined"

[flex]

Hello,

I cannot start NodeBB using the following Dockerfile. I have a weird error that I never saw in the forum or GitHub:

[...]
Schema update complete!

Note: I tried also cloning the main GitHub repo, same error.

Start Redis and NodeBB

docker run --name nodebb-redis -d --rm redis
docker build -t my/nodebb:debian .
docker run --name nodebb -ti --rm -p 4567:4567 my/nodebb:debian

Once started, I connect inside the docker container to debug.
The following commands are running with success:

node ./nodebb build
node ./nodebb upgrade

But impossible to start nodebb using either:

node ./nodebb start
node app.js
node loader.js

I tried also to start from the official Dockerfile with some edit, another error (EADDRINUSE).

The config file generated after the web installer is:

{
    "url": "http://sub.domain.tld",
    "secret": "2fe83efb-3317-4e9e-98c4-b590353711df",

        "port": "6379",
        "password": "",
        "database": "0"
    }
}

If I try to stop:

# node ./nodebb stop
NodeBB is already stopped.

If I search for running processes:

b# ps -aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND

It seems that nodebb is already running, but why?

[PitaJ]

The web installer automatically starts NodeBB when it finishes.

@PitaJ I know that, but this is not the error I am facing.
Actually, I opened a parallel GitHub issue (for my first message) and they find out the root cause.

My configuration file is not correct, the "session_store" should be an object like "redis" and not a simple string.
