        return $this->extension;

The expression $this->extension; of type Symfony\Component\DependencyInjection\Extension\ExtensionInterface|false adds false to the return on line 45 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.
