I have created a zend-expressive project, I would like to integrate Doctrine, I am using this documentation
> **[Generating HAL for Doctrine Entities - zend-expressive-hal - Zend Framework Docs](https://docs.zendframework.com/zend-expressive-hal/doctrine/)**
but I get this error:
Too few arguments to function Album \ Handler \ ListAlbumsHandler :: \_\_ construct (), 0 passed in C: \ xampp \ htdocs \ expressive \ vendor \ zendframework \ zend-expressive \ src \ MiddlewareContainer.php on line 64 and exactly 4 expected
what did i do wrong?

First of all, you might want to read the latest docs here: [https://docs.mezzio.dev/mezzio-hal/doctrine/](https://docs.mezzio.dev/mezzio-hal/doctrine/)
zend-expressive is renamed to mezzio and the zend-expressive components will not get any more updates.
Without seeing any code and only that error message, I’m guessing you forgot to create a factory for the album handler and add it to the service container. You can find more information about factories here: [https://docs.mezzio.dev/mezzio/v3/features/container/config/#factories](https://docs.mezzio.dev/mezzio/v3/features/container/config/#factories)
