light.run method leads to undefined method `call' for nil:NilClass (NoMethodError)

[DhawalSawla]

Describe the bug

When I run this small code below:

light = Stoplight('http-api')
light.run { 22.0 / 7  }

it leads to the below error:
/Users/thewall/.gem/ruby/3.0.0/gems/stoplight-3.0.1/lib/stoplight/light/runnable.rb:56:in run_code': undefined method call' for nil:NilClass (NoMethodError)

To Reproduce
Steps to reproduce the behavior.

Expected behavior
I expected the above method to run properly without giving any error.

Screenshots

I added the gem in my gemfile like this:
gem 'stoplight'

I also see it in my gemfile.lock:
stoplight (3.0.1)

Environment (please complete the following information):

• OS: macOS 13.5 (22G74)
• Ruby - ruby 3.0.2p107 (2021-07-07) [x86_64-darwin17]
• Version [e.g. 3.0.1]
• Rails 6.0.5.1

Additional context
Add any other context about the problem here.

It results in the same error for the stoplight gem version 2.2.1.

[bolshakov]

You use Stoplight syntax that is not compatible with your Stoplight version. I suggest you use the latest Stoplight version (4.1). If, for some reason, you cannot use Stoplight 4.1, you need to rewrite your example the following way:

- light = Stoplight('http-api')
+ light = Stoplight('http-api') { 22.0 / 7  }
- light.run { 22.0 / 7  }
+ light.run

You can find more details in the update guide https://github.com/bolshakov/stoplight/blob/master/UPGRADING.md

Thanks! The above code works. I still get below error when I add around_action method to my controller.

All right, I have confused you with this backward incompatible change.

• For Stopliht 3.x, see the documentation here https://github.com/bolshakov/stoplight/tree/release/v3.x
• For Stopliht 4.x, see the documentation here https://github.com/bolshakov/stoplight/tree/master

[bolshakov]

I released v3.0.2, which shows a better error message in such cases. let me know if you have any further questions
