Issue Error opening Extensions

[ismaeldc]

Hi,
I encountered a similar error when trying to access the page for any of my extensions : ERROR: Declaration of DI\CompiledContainer::get($name) must be compatible with DI\Container::get(string $id): mixed (CompiledContainer.php:41)

I solved it by disabling then updating the Node.js extension - Toolkit
Here are the commands I used as root:
* extenions page test: OK
My other extensions, including Grafana mentioned above, do not cause this error.

Perfect!!! The problem nodejs. Thanks.

In my case, Node.js was never installed, I don't use it. But for control, I installed it ("Phusion Passenger server" was also installed), it took a little bit long to be installed. Of course the error issue was not solved.

Then I uninstalled "NodeJS support" and "Phusion Passenger server", but still the same, when I click Extensions, Mail Queue, Monitoring, etc., it's still error;
ERROR: Declaration of DI\Definition\Source\DefinitionFile::getDefinition(string $name) must be compatible with DI\Definition\Source\DefinitionArray::getDefinition(string $name): ?DI\Definition\Definition (DefinitionFile.php:36)

And I never installed Grafana, too. So, error is going on and I'm getting more nervous. Because I tried add a domain, it's added, but I couldn't install Let's Encrypt, still error. The VPS is dying

I enabled Debug mode in Plesk. I made "/var/log/plesk/panel.log" empty (true > panel.log). Then I clicked Extensions, same error. But panel.log file have hundreds of lines in a second, it's impossible to find the error message.
