When does this happen?
IF LLM-generated JSONPath query uses JavaScript array methods like `.includes()` or `.indexOf()`, which are not valid JSONPath operators, causing a `JsonPathParserError`.
How others solved it
THEN When using `JSONQueryEngine`, instruct the LLM to generate only standard JSONPath operators (e.g., `==`, `!=`, `in`, `<`, `>`) for filtering arrays. Alternatively, post-process the LLM output to replace `.includes()` with the `in` operator or use native JSONPath syntax like `@.courseTags in ['term']`.
// Avoid: $.courses[?(@.courseTags.includes('Machine Learning'))]
// Use: $.courses[?(@.courseTags in ['Machine Learning'])]Related patterns
