        if (null === $this->extension) {
            $extension = $this->createContainerExtension();

            if ($extension instanceof ExtensionInterface) {
                $this->extension = $extension;
            } else {
                $this->extension = false;
            }
        }

        return $this->extension;

The expression $this->extension; of type Symfony\Component\DependencyInjection\Extension\ExtensionInterface|false adds false to the return on line 42 which is incompatible with the return type declared by the interface Symfony\Component\HttpKernel\Bundle\BundleInterface::getContainerExtension of type Symfony\Component\DependencyInjection\Extension\ExtensionInterface|null. It seems like you forgot to handle an error condition.
