$this->renderingContext of type object<TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface> is not a sub-type of object<TYPO3\CMS\Fluid\Core\Rendering\RenderingContextInterface>. It seems like you assume a child interface of the interface TYPO3Fluid\Fluid\Core\Rendering\RenderingContextInterface to be always present.
