Composer step reporting issues with $_WEB_ROOT

No wait, that seems to be a comment indicating what commands are being run. In that case I'm clueless as to why the pipeline is failing.

The Composer install and require drush section is collapse by default.

The problem is there:

Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - Root composer.json requires drupal/core-dev 11.2.0 -> satisfiable by drupal/core-dev[11.2.0].
    - Root composer.json requires drupal/core-recommended 11.2.0 -> satisfiable by drupal/core-recommended[11.2.0].
    - Root composer.json requires jangregor/phpstan-prophecy ^1.0 -> satisfiable by jangregor/phpstan-prophecy[1.0.0, 1.0.1, 1.0.2].
    - drupal/core-dev 11.2.0 requires mglaman/phpstan-drupal ^2.0.7 -> satisfiable by mglaman/phpstan-drupal[2.0.7].
    - jangregor/phpstan-prophecy 1.0.0 requires phpstan/phpstan ^1.0.0 -> satisfiable by phpstan/phpstan[1.0.0, ..., 1.12.x-dev].
    - mglaman/phpstan-drupal 2.0.7 requires phpstan/phpstan ^2.1 -> satisfiable by phpstan/phpstan[2.1.0, ..., 2.1.x-dev].
    - Conclusion: don't install jangregor/phpstan-prophecy 1.0.1 (conflict analysis result)
    - Conclusion: don't install jangregor/phpstan-prophecy 1.0.2 (conflict analysis result)
    - Conclusion: don't install one of phpstan/phpstan[2.1.17], jangregor/phpstan-prophecy[1.0.0] (conflict analysis result)
    - You can only install one version of a package, so only one of these can be installed: phpstan/phpstan[1.0.0, ..., 1.12.x-dev, 2.0.0, ..., 2.1.x-dev].

Thanks! For future reference, where can I find this output myself?

It’s in the output of the job, but as it is collapsed by default you may have missed it.

Ah yes, I was unaware of that feature. Thanks!
