`fetch': key not found: :path (KeyError)

[joshmfrankel]

Describe the bug

Running Rails tests or server produces the following error fetch': key not found: :path (KeyError).

I'm using dry-rails but the issue seems to stem from lib/dry/system.rb:23 (dry-system)

To Reproduce

I'm using a super basic docker + rails repo and am able to recreate issue once I add gem 'dry-rails' to the Gemfile. Rails server and testing stops working. See Repo here: https://github.com/joshmfrankel/rails-7-docker

Expected behavior

Expect tests and server to execute and dry-system to properly build

My environment

• Ubuntu 20.04.3
• Dry-rails - 0.4.0
• Ruby - 3.1.0
• Rails - 7.0.1
• Minitest 5.15.0
• Nodejs - 16.13.1
• Docker 20.10.12
• docker-compose 1.29.2

dry-system 0.23 had a lot of big changes. I'd recommend you pin to 0.22 within your app for now, it thank you for raising this issue here for us to fix.

[joshmfrankel]

@timriley Thank you for the speedy and efficient response. That solved it for me 💯. We've at least got a workaround now

gem "dry-rails", "~> 0.3"
gem "dry-system", "<= 0.22"

[solnic]

I'm gonna fix it and push a new release tomorrowish

[timriley]

@solnic i promise to drop breaking dry-rails soon ;)

[solnic]

@timriley haha yeah, one day we'll have cross-repo automated test suites, one day

[solnic]

This is a bit more involved, I started upgrading the whole thing in #52

[solnic]

OK I released 0.5.0

[timriley]

Thank you @solnic! 🙏🏼
