Error starting server mix phx.server

annrap1d · September 29, 2023, 11:53pm

Hi there,

I am setting up a new staging instance on webdock.io. I was able to create the database and run the migrations. When i tried to start the server, I am getting error.

I haven’t used Elixir’s logger in a while but is $request valid? Has it worked before? Does it work if you remove it?

kokolegorille · October 1, 2023, 1:45am

Maybe it’s related to the Elixir version (and BEAM)…

Which one do You have?

annrap1d · October 1, 2023, 2:10am

Hi,

I have the following versions

Erlang/OTP 25 [erts-13.1.5] [source] [64-bit] [smp:48:5] [ds:48:5:10] [async-threads:1] [jit:ns]

Interactive Elixir (1.15.6) - press Ctrl+C to exit (type h() ENTER for help)

annrap1d · October 1, 2023, 2:12am

It worked fine on linode vps. I am migrating to webdock and I am running into issues. the linux kernel, Erlang and elixir versions are all the same.

kokolegorille · October 1, 2023, 10:25am

If You can, You could try with Elixir 1.14 or the latest 1.15…

I think I had something similar that could be resolved by changing version.

Two things that stand out in this error message:

something is passing a format to the logger that has a $request variable in it. That’s not supported:

github.com

elixir-lang/elixir/blob/60efbf751d3bedbe1851ac8c701a807d66fe340d/lib/logger/lib/logger/formatter.ex#L39-L46


      
          The valid parameters you can use are:
          
            * `$time`     - the time the log message was sent
            * `$date`     - the date the log message was sent
            * `$message`  - the log message
            * `$level`    - the log level
            * `$node`     - the node that prints the message
            * `$metadata` - user controlled data presented in `"key=val key2=val2 "` format

I’d start by looking into where this configuration is coming from, and how it works currently on the running servers.

the (1.14.0) tells me this stacktrace isn’t from the Elixir version you’re trying to run
