Fix malformed query exception on neptune edge_fulltext_search

[dontang97]

Summary

In the logic for performing full-text search on edges, if a document is found in OpenSearch’s edge_name_and_fact index, the UUID of that document is used as a parameter to further query Neptune for the related triplet. The MalformedQueryException occurs at this stage due to a syntax error in the Neptune query. In the query source code shown below, the cause of the MalformedQueryException is that the filter_query contains its own WHERE clause, resulting in the overall query having two WHERE clauses, which is invalid syntax.

error log: graphiti_core.driver.neptune_driver: Error executing query: {'message': 'An error occurred while executing the query.', 'details': "An error occurred (MalformedQueryException) when calling the ExecuteOpenCypherQuery operation: Invalid input 'H': expected 'i/I' (line 6, column 27 (offset: 231))"}
