Describe the bug

When calling the search_engine = LocalSearch( llm=llm, context_builder=context_builder, token_encoder=token_encoder, llm_params=llm_params, context_builder_params=local_context_params, response_type="paragraph", # free form text describing the response type and format, can be anything, e.g. prioritized list, single paragraph, multiple paragraphs, multiple-page report )

For some (not all) complex questions.

result = await search_engine.asearch("Explain article 14 and list all services?") print(result.response)

We get error: ValueError: No objects to concatenate
