Getting this after Rails 8 upgrade - cannot load such file -- mutex_m (LoadError)

Looks like mutex_m is a dependency for pusher. But Rails 8 upgrade has removed this library.

I added this library in the Gemfile, and it fixed the issue.

mutex_m is no longer a part of the default gem set since Ruby 3.4.0 and needs to be included in the Gemfile

mutex_m is used by the httpclient gem, which hasn't been updated since 2016 and is a dependency of the pusher-http-ruby gem.
