Codeception: A void function must not return a value error since 4.1.2

[Jamesking56]

Caused by #5862

What are you trying to achieve?

Return types on generated actions for methods that return void should not use return since you cannot return a void:

public function voidMethod(): void {
    $this->getScenario()->runStep(new \Codeception\Step\Action('voidMethod', func_get_args()));
}

What do you get instead?

public function voidMethod(): void {
    return $this->getScenario()->runStep(new \Codeception\Step\Action('voidMethod', func_get_args()));
}

This causes PHP errors:

Fatal error:  A void function must not return a value

Details

Upgrading my project to 4.1.3 still has this problem. This needs reopening.

Can confirm, still getting "A void function must not return a value in /var/www/html/tests/_support/_generated/ApiTesterActions.php line 5361"

Have you ran codecept build after upgrade?

[Jamesking56]

Yeah @Naktibalda. codecept build always runs successfully but running tests crashes with the fatal error in 4.1.3 but doesn't crash after applying patch from #5880
