TypeError: no implicit conversion of Array into String about webrick HOT 5 CLOSED

Do you need to return a response or something?

from webrick.

No, I just did this to check the environment. (Not to be used in production). Am doing something you're not supposed to do in this context? See also original question: Why is this happening, and what is the proper fix?

from webrick.

What framework is

get '/' do
  content_type 'text/plain'
  request.env.each do |k, v|
    puts "#{k}: #{v}"
  end
end

Looks like Sinatra. The issue is the get block is not returning one of Sinatra's expected return values. See the Return Values section of https://sinatrarb.com/intro.html . This appears to be a bug in the app, not in Webrick.

Yes, Sinatra. Aha, so it's not the code itself, but what is returns that causes problems down the line. I didn't know there was a return value. Not an issue then, or there could possibly be a warning/exception for this. Up to the devs.
