No Credo errors

Actual outcome

Since going from 1.7.1 to 1.7.2 we are now getting a ton of errors from Credo.Check.Warning.MissedMetadataKeyInLoggerConfig that look like this:

┃ [W] ↗ Logger metadata key aid not found in Logger config
┃       lib/libs/quiltt.ex:85 #(Libs.Quiltt.upsert_account)

We have all these specified in our config/config.exs like so:

config :logger, :console,
  format: "$time $metadata[$level] $message\n",
  metadata: [
    :account,
    :admin,
    :aid,
    ...
  ]

Same issue here.

:logger |> Application.get_env(:default_formatter) |> Keyword.get(:metadata) returns the correct metadata list in the same environment.

@Billzabob Ah, we changed the key that is read to :default_formatter for newer versions of Elixir. Does it work when you change your logger config to the new key?

@tcitworld When you are writing "in that environment", is that the same env Credo is run in?

[ViseLuca]

@rrrene yeah, I tried on my project to add the metadata in every environment file but nothing is changing. Same error of @Billzabob

Changing :console to :default_formatter worked for me on a clean phoenix install

ie.
`$ mix credo -v
1.7.2

$ elixir -v

all good

Question? is this the correct way to clear the 'issue'? I don't know the impact to the rest of the application when changing :console to :default_formatter

[rrrene]

@Billzabob @tcitworld @ViseLuca Thanks for reporting this 😀 It should now be fixed on master.

You can try this by setting the Credo dep to

{:credo, github: "rrrene/credo"}

Please report back if your issue is solved! 👍

@rhammer1 No, we don't want people to change their config.exs for Credo to work. We f'ed up on this one 🤔

[ViseLuca]

{:credo, github: "rrrene/credo"}

Yeah issue is solved! I tried right now, thank you very much! 😄

[rrrene]

@Billzabob @tcitworld @ViseLuca @rhammer1 Fix is live as part of 1.7.3. Sorry for the inconvenience. ✌️

Please feel free to re-open if there are any problems 👍

[rhammer1]

Credo 1.7.3 fixes the problem, thanks!
