Generation Failing With `zsh: trace trap xcodegen`

I'm trying to have my project build multiple schemes which all use different configurations whose values are stored in .xcconfig files. I have some luck with using configVariants within my target but it appears to require creating both release and debug variations for each build configuration file. Essentially I'm trying to replicate an existing project and it only has separate schemes with their own configuration files.

I looked into the top-level schemes object and have the following below however when I run xcodegen in the terminal, I'm receiving zsh: trace trap xcodegen. I don't get any validation errors on the project.yml file itself, just this error. Can anyone possibly let me know if this is a bug or where I'm going wrong with my setup?

Thanks

name: MyApp

configs:
  Staging: debug

configFiles:
  Staging: MyApp-Staging.xcconfig

schemes:
  MyAppStaging:
    build:
      targets:
        MyApp: all
    run:
      configFile: Staging

targets:
  MyApp:
    type: application
    platform: iOS
    sources:
      - path: App

Start by reproducing the trace trap with the shown project.yml, MyApp-Staging.xcconfig, Staging configuration, and MyAppStaging scheme using xcodegen. Compare the configuration and scheme definitions with the expected XcodeGen format; done means the project generates successfully without the trace trap and preserves the requested scheme configuration.
