Magento 2.3 – Fix PHP Fatal Error in InitParamListener

magento-upgrademagento2magento2.3

I have updated the version of magento from 2.3.4 => 2.3.7 but. Composer commands runs successfully with no error. But now when I try to run magento commands eg. s:up or compile it does not work and returns an error :

PHP Fatal error: Class Magento\Setup\Mvc\Bootstrap\InitParamListener
contains 1 abstract method and must therefore be declared abstract or
implement the remaining methods
(Laminas\ServiceManager\Factory\FactoryInterface::__invoke) in
/htdocs/setup/src/Magento/Setup/Mvc/Bootstrap/InitParamListener.php on
line 32

I tried composer update , composer install , removed vendor folder and then composer install but no luck.

Please help me to solve the issue I will be very thankful to you.

To fix this issue, copy the setup folder from magento 2.3.7 another project or download it from magento git repo: https://github.com/magento/magento2/tree/2.3.7/setup

It works for all others magento versions, just change 2.3.7 to your magento upgrade version. For example, you want to upgrade to magento 2.4.3, the setup folder can get in https://github.com/magento/magento2/tree/2.4.3/setup

Magento – Magento 2 module not registering and causing CLI to fail

If you get the error "Decoding failed: Syntax error" I would check the module's composer.json file. For me this has happened a couple of times due to a comma that is not needed inside the require parameters.

If your composer file has this:

"require": {
    "php": "~5.6.0|7.0.2|~7.0.6",
    "magento/module-catalog": "101.0.*",
    "magento/module-checkout": "100.1.*",
},

You will see this error every time. Instead, remove the comma on your last required value. It should now look like this.

"require": {
    "php": "~5.6.0|7.0.2|~7.0.6",
    "magento/module-catalog": "101.0.*",
    "magento/module-checkout": "100.1.*"
},

I haven't tested but this error would probably happen for each parameter if the last value has a comma at the end.

Magento 2.1 Error – Area Code Not Set

Take a look here:

Magento\Framework\ObjectManager\ObjectManager->get() at /opt/bitnami/apps/magento/htdocs/app/code/J2t/Rewardpoints/Observer/ProcessSaveModel.php:21

Looks like this module is trying to grab the Object Manager which might be triggering the error if that area code is not set. In my comment, i linked to a solution i found to this error for an extension i was using. Might help you out here as the call to the Object Manager is happening in an Observer.

Here is that link again: Magento 2 "Area code not set" warning in 3rd party module
