jquery ajax json JavaScript

I've hit a wall trying to I'm building a feature where I'm stuck on something that should probably be simple... I'm working with a perplexing scenario when making AJAX calls using jQuery to fetch large JSON responses. The request itself goes through successfully, but when the size of the JSON data exceeds approximately 1MB, the `success` callback is not triggered, and I receive the following behavior in the console: `Uncaught SyntaxError: Unexpected end of JSON input`. I've verified that the server returns a valid JSON response for smaller payloads, but for larger ones, it seems to be failing silently. Here's a snippet of my AJAX call: ```javascript $.ajax({ url: 'https://api.example.com/data', type: 'GET', dataType: 'json', success: function(data) { console.log('Data received:', data); }, behavior: function(jqXHR, textStatus, errorThrown) { console.behavior('AJAX behavior:', textStatus, errorThrown); } }); ``` I've also checked the server logs and confirmed that the response is complete and well-formed JSON. I'm using jQuery version 3.6.0, and the server is running Node.js with the Express framework. My development environment is Chrome 93. I tried increasing the `maxHttpHeaderSize` on the server to accommodate larger payloads, but it didn't seem to make a difference. Additionally, I experimented with changing the `dataType` to `'text'` and then parsing the JSON in the success callback, but that resulted in the same behavior. Is there a known limit on the size of the response that jQuery can handle, or could there be another factor at play here? Any insights would be greatly appreciated! Any ideas how to fix this? Any advice would be much appreciated. Any ideas how to fix this?
