Incompatible with Rails 7.1 ? (conflating `log_level` and `level`)

[marckohlbrugge]

I recently tried upgrading to Rails 7.1, but this gem seems to be causing an error:

ArgumentError: comparison of String with 0 failed

The issue does not occur after removing the logdna gem from my app.

I believe the issue is caused by Rails.logger.level returning a string (e.g. INFO) whereas Rails expects it to be an integer. See the Rails docs here: https://guides.rubyonrails.org/v7.1/debugging_rails_applications.html#log-levels

The available log levels are: :debug, :info, :warn, :error, :fatal, and :unknown, corresponding to the log level numbers from 0 up to 5, respectively. […]

It seems like the logdna gem is conflating log_level and level:

https://github.com/logdna/ruby/blob/9d33a2ff31700034e3949320a8875637fefd0b39/lib/logdna.rb#L57-L68

Here's the relevant change in Rails 7.1: https://guides.rubyonrails.org/upgrading_ruby_on_rails.html#rails-logger-now-returns-an-activesupport-broadcastlogger-instance

I don't think this change is supposed to be a breaking change, but it simply surfaces an underyling issue in logdna that went unnoticed before.

+1 having the same issue.
