Detected `require 'bundler/inline'` - please replace with `r

Error message

Detected `require 'bundler/inline'` - please replace with `require 'windmill/inline'`.
Your Gemfile syntax will continue to work as-is.

What it means

Raised by the Ruby dependency resolver when the script requires 'bundler/inline' directly. Windmill injects its own compatible inline runner ('windmill/inline'); the stock bundler one would bypass the proxy that enforces dependency management. The message is instructive by design: gemfile block syntax keeps working unchanged, only the require line must be swapped.

Solutions

1. Replace `require 'bundler/inline'` with `require 'windmill/inline'`
2. Leave the gemfile block syntax as-is — it is fully supported
3. Re-run the job after the one-line require change
