Error in developer mode: Argument #2 ($validationState) must be of type ValidationStateInterface, null given

Question

I get below error after I do bin/magento setup:upgrade on my local env. The only workaround I got so far is to run bin/magento setup:di:complile. After running di compile the error is gone unit I run setup:upgrade again. I am in developer mode.

What is the root problem, and how can I solve it?

Answer 1

Instead of running the command. Please solve the error that causes the root issue. It seems you have a Type Error Occurred When creating an object I Dom object in the constructor of the class.

If your Magento 2 version is not the latest version so it means the issue is in your custom module is not Magento 2.4.* compatible.

You should update your custom modules to the updated version.

Another way around to fix this possible solutions are:

• Run the setup upgrade again and then compile your code.
• Find out which class is not compatible with your class that is causing the issue:

Open the class data/web/application/vendor/magento/framework/ObjectManager/Factory/AbstractFactory.php on line 121, Add the below line of code, and it will give you the Class name and method name.

if($dataType === null || empty($dataType)){echo $serviceClassName.'<>'.$serviceMethodName . PHP_EOL;}

Putting it here in case someone needs it.

• Check the PHP version is compatible with your Magento version.
• This is the error sometimes when the constructor is called with a missing parameter.
• Quick fix if nothing works try to setup an empty array for the required null parameter and see what happens after compilation.
• Perhaps as per the M2.4.6, optional parameters come after the mandatory.

Thanks

Answer 2

Can please run below commands and then run compile command

chmod -R 777 var/ generated/ pub/
rm -rf var/cache/* var/page_cache/* var/view_preprocessed/* generated/*
chmod -R 777 var/ generated/ pub/

compile command

php bin/magento setup:di:complile

It seems there was a module active which was doing things with XML/XSD. I think it was a fix for a pre version of 2.4.5. After upgrade, this module was not necessary, but it was still in the repo. Deleting it fixed the issue.
