Strange module exception error

[tommasop]

Environment

elixir 1.14.5
OTP 25.3.2.12
phoenix 1.17.0

Steps to Reproduce

We have a plug exception defined like this:

  defmodule UnauthorizedRequestError do
    @moduledoc """
    Error raised when the Admin request is not authorized.
    """

    defexception message: "Admin request unauthorized", plug_status: 403
  end

And have filtered < 500 errors in before_send like this:

  def filter_non_500(%Sentry.Event{original_exception: exception} = event) do
    cond do
      Plug.Exception.status(exception) < 500 ->
        false

      # Fall back to the default event filter.
      Sentry.DefaultEventFilter.exclude_exception?(exception, event.source) ->
        false

      true ->
        event
    end
  end

Expected Result

I expect not to see any error logged in Sentry

Actual Result

We have many of these errors recorded:

I cleaned up the error, it's here in case it makes it easier to debug:

I’m a little stumped by this to be honest. I don't see cowboy logging anything on its own in cowboy_stream_h.erl, which could explain this log being reported.

In any case, could you share your Sentry config in case it might help debug this? Also, just putting it out there, do you have a way to consistently reproduce this?

cc @ninenines in case this is obvious to you 😄

[tommasop]

@whatyouhide this is the runtime configuration we have for sentry:

config :sentry,
    dsn:
      "https://720a295a41be850479e6fc8eed51f841@o4507304654995456.ingest.de.sentry.io/4507390105813072",
    environment_name: get_env("DEPLOYMENT_ENV"),
    enable_source_code_context: true,
    root_source_code_paths: [File.cwd!()],
    before_send: {IxiCenter.SentryEventFilter, :filter_non_500}

I will try to setup a minimal environment to reproduce this.

In the meantime is it possibile to filter these errors out in order to:

1. Reduce noise
2. Avoid to get over threshold cap

Thanks a lot

[whatyouhide]

You can filter them out yourself in your before_send, by matching on parts of the message. I don't think it's a good idea to filter them out in Sentry before figuring out what is actually happening here 🙃
