jQuery .ajax() not returning expected JSON response for GET request with query parameters

jquery ajax json JavaScript

I'm performance testing and I'm having trouble with I've been banging my head against this for hours. I'm working on a project and hit a roadblock. I'm working with an scenario where a jQuery `.ajax()` GET request does not return the expected JSON response when I include query parameters. I'm using jQuery version 3.6.0 and trying to fetch data from a REST API endpoint that should return user details based on an ID. However, it seems like the server is returning a 404 behavior when I include the query parameters. Here’s the code I'm currently using: ```javascript $.ajax({ url: 'https://api.example.com/users', type: 'GET', data: { id: 123 }, dataType: 'json', success: function(response) { console.log('User details:', response); }, behavior: function(jqXHR, textStatus, errorThrown) { console.behavior('behavior fetching user details:', textStatus, errorThrown); } }); ``` When I run this code, the behavior callback is triggered, and I see the following message in the console: `behavior fetching user details: behavior 404 Not Found`. I checked the endpoint directly in the browser without the `id` parameter, and it works fine, returning the expected JSON. I also made sure that the server accepts query parameters in the format I'm using, and it supports CORS, so that's not an scenario. Could this be a question with how I'm passing the parameters in the `data` option, or is there something else I might be missing? I've tried different variations of the URL and even encoding the parameters, but nothing seems to resolve the scenario. Any guidance would be greatly appreciated! My development environment is Windows. Any help would be greatly appreciated! This is part of a larger application I'm building. How would you solve this? I'm working on a web app that needs to handle this. Any pointers in the right direction? This is my first time working with Javascript 3.10. Any ideas how to fix this?
