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
    - zendframework/zend-component-installer[2.1.1, ..., 2.1.2] require composer-plugin-api ^1.0 -> found composer-plugin-api[2.0.0] but it does not match the constraint.
    - Root composer.json requires zendframework/zend-component-installer ^2.1.1 -> satisfiable by zendframework/zend-component-installer[2.1.1, 2.1.2].

You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2.

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.
