Dependabot can't resolve your PHP dependency files

[dependabot-preview]

Dependabot can't resolve your PHP dependency files.

As a result, Dependabot couldn't update your dependencies.

The error Dependabot encountered was:

Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - Root composer.json requires php-standard-library/psalm-plugin ^1.0 -> satisfiable by php-standard-library/psalm-plugin[1.0.0].
    - php-standard-library/psalm-plugin 1.0.0 requires azjezz/psl ^1.5 -> satisfiable by azjezz/psl[1.5.0] from composer repo (https://repo.packagist.org) but azjezz/psl[1.0.0+no-version-set] from root package repo has higher repository priority. The packages with higher priority do not match your constraint and are therefore not installable. See https://getcomposer.org/repoprio for details and assistance.

If you think the above is an error on Dependabot's side please don't hesitate to get in touch - we'll do whatever we can to fix it.
