OK running into a problem here When I

OK, running into a problem here. When I create a DecomposeQueryTransform and a TransformQueryEngine, and then query it with a string (as per the examples[0]), I get the error "Invalid Prompt Type". This seems to be because by default the DecomposeQueryTransform initializes itself with a DecomposeQueryTransformPrompt, which by default has prompt_type=PromptType.CUSTOM, which is not in the list of prompt types checked in MockLLMPredictor._predict(). What am I doing wrong here? How do I fix this?
