When does this happen?

IF Using array methods like `includes` or `indexOf` in JSONPath queries within JSONQueryEngine causes a JsonPathParserError.

How others solved it

THEN Replace `includes` with the JSONPath `in` operator, and `indexOf` with a filter expression using `==` or `in`. For example, change `@.courseTags.includes('Computer Science')` to `@.courseTags in ['Computer Science']`. For `indexOf`, use `'Machine Learning' in @.courseTags` or `@.courseTags[?(@ == 'Machine Learning')]`.

# Before (causes error):
# $.courses[?(@.courseTags.indexOf('Machine Learning') != -1)].courseName

# After (works):
$.courses[?('Machine Learning' in @.courseTags)].courseName
