Explanation:
userId: $.data.users[?(@.phoneNumber == '+1 (555) 123-4567')].userId
currentPage: $.data.currentPage
The JSONPath mapping must match the structure shown in the API response. The userId variable is not a simple top-level property; it sits inside the users array. The expression must filter the users array for the object whose phoneNumber equals +1 (555) 123-4567 and then return that object's userId. That is why the filtered JSONPath expression using $.data.users[?(@.phoneNumber == '+1 (555) 123-4567')].userId is the correct mapping. The currentPage variable is directly under data, so the correct expression is $.data.currentPage.
Expressions such as $.currentPage miss the data wrapper, and $.data.currentPage.number assumes currentPage is an object with a number property, which the response does not show. $.data.user[0] .userId is also wrong because the array name in the response is users, not user, and it would take the first user rather than the matching phone number.
