Hi, I am tryin to use PrevNextNodePostprocessor to retrieve more nodes from the same document but I get raise ValueError(f"doc_id {doc_id} not found.")
ValueError: doc_id e4e59a11-a8d6-4141-b775-9b60d8af1788 not found.
whenever I use this option. This is the code I implemented to use this feature: node_postprocessors =[ PrevNextNodePostprocessor(docstore=storage_context.docstore,num_nodes=2,mode="both")]
First I thought that maybe some retreived nodes are the first or the last chunk of document and there is no next/prev node related to them but it seems this is not the main problem. Any I idea what am I doing wrong?
Check if the doc_id exists in your docstore. You can do this by querying the docstore directly. You can do this with the following code: try: document = storage_context.docstore.get_document(doc_id) print(f'Document with ID {doc_id} found in the docstore.') except ValueError: print(f'Document with ID {doc_id} not found in the docstore.')
Thanks@rahul for the reply, but it seems that the document with that specific doc_id does not exist. Why does the function gets the wrong doc_id for that node, since i have no control over it and the function should have found the node's document id by itself. What could cause this issue?
