Ruby 3.4.0 frozen string warnings

[hlascelles]

This gem mutates strings, which emits Warnings in ruby 3.4:

Here is a line where it happens: https://github.com/rollbar/rollbar-gem/blame/4694a35aba7518b30097a41fab15653d07cd73c0/lib/rollbar/middleware/js.rb#L126

gems/rollbar-3.4.1/lib/rollbar/middleware/js.rb:126: warning: literal string will be frozen in the future (run with --debug-frozen-string-literal for more information)

The gem should not mutate any strings. See https://blog.saeloun.com/2024/05/20/frozen-string-literal/

SDK-519 Ruby 3.4.0 frozen string warnings

Not only warnings.

I'm using ruby 3.4.5 and have RUBYOPT="--enable-frozen-string-literal" set.
Running rails generate rollbar <token> during installation raises can't modify frozen String: "access token: " (FrozenError)

I can workaround it currently with RUBYOPT="" rails generate rollbar <token>

FYI, the error is located at

/rollbar-3.6.2/lib/generators/rollbar/rollbar_generator.rb:41:in 'Rollbar::Generators::RollbarGenerator#create_initializer': can't modify frozen String: "access token: " (FrozenError)

Yes, the warning/error is very annoying,

Maybe something like this can help. WDYT?

  response.to_enum.map(&:to_s).join
