The community member is experiencing an issue where their query to a specific index is returning "None" regardless of the query. The comments suggest that this could be due to the SimilarityPostprocessor not being set correctly, or that the index and document files are being overwritten and emptied, resulting in no information to query. One community member found that the issue was solved, but did not provide details on the solution.
Have you set SimilarityPostprocessor with some value? As it will only pass the nodes to LLM which crosses the value. If no nodes breach the threshold no LLM calls happen and you get None.
I found that when i'm creating new indexes, my index json file is being overwritten and document json file is being completely emptied. so essentially there is no information to query. Any idea why this would be occurring? I'm using vectostoreindex to create the indexes.
