PHP message: PHP Fatal error: Uncaught TypeError

[matejslo]

Hi, for some reason MSP dev tools module when enabled returns HTTP ERROR 500.

I checked the NGNIX logs and I see this error:

2022/03/07 09:54:12 [error] 8929#8929: *47794 FastCGI sent in stderr: "PHP message: PHP Fatal error: Uncaught TypeError: Argument 1 passed to MSP\DevTools\Plugin\PhpEnvironment\ResponsePlugin::aroundSendContent() must be an instance of Zend\Http\PhpEnvironment\Response, instance of Magento\Framework\HTTP\Php$

Hello @matejslo,
we can't reproduce your issue on a clean Magento 2.4.3-p1 instance. Can you provide some more elements to help us?

Is this happening on a particular page? Are you using Luma or a custom theme? Do you have any 3rd party module that could interfere with our module?

[matejslo]

We will try to get more info. I went to some old (aproox. 1 month) commit and the problem was gone so it must be related to some third party module or module update that we installed.

We have a custom theme, but the problem happens also on default luma theme.

I will get back to you when we have more info. We will try to find the source of the problem commit by commit.

Thank you for now.
