has anyone taken an existing elasticsearch (or any) index and retrofitted llamaindex on top of it? i am trying to do that with an existing elasticsearch index i have, but keep running into
File "C:\Python311\Lib\site-packages\llama_index\vector_stores\elasticsearch.py", line 542, in aquery f"Could not parse metadata from hit {hit['_source']['metadata']}" ~~~~~~^^^^^^^^^^^^ KeyError: 'metadata'
understandably because the format of the metadata in my Elasticsearch index is not the expected format for the ElasticsearchStore class in LlamaIndex. how do you get around this without having to re-index everything?
