Necessary steps:

• replace resource: '@FrameworkBundle/Resources/config/routing/errors.xml' with resource: '@FrameworkBundle/Resources/config/routing/errors.php'

In other words, replace xml with php in these files: https://github.com/api-platform/demo/blob/4.2/api/config/routes/framework.yaml and https://github.com/api-platform/demo/blob/4.2/api/config/routes/web_profiler.yaml
