Problems on Symfony 5.0

[svaningelgem]

I just did a composer update and got the following messages:

  - Updating symfony/event-dispatcher (v4.2.1 => v5.0.7): Downloading (100%)

Nothing special, just a major version update, but it seems something changed under the hood:

TypeError: Argument 1 passed to Symfony\Component\EventDispatcher\EventDispatcher::dispatch() must be an object, string given, called in <my project>/vendor/kriswallsmith/spork/src/Spork/ProcessManager.php on line 94 and defined in <my project>/vendor/symfony/event-dispatcher/EventDispatcher.php:48

BTW, how I solved it is via:

composer require symfony/event-dispatcher ^4

That will limit event-dispatcher to the major version 4.

Check https://github.com/TheLevti/phpfork. Its a fork of this repo where I try to keep it up to date. Its still work in progress and hopefully I can provide a pull request back into this one.
