How to Fix: Ajax request returns 200 OK, but an error event is fired instead of success

SEO meta description 140-155 characters.

Quick Answer: 1-2 sentences of direct conversational advice.

In your jQuery code, there is a typo in the success callback function. The correct spelling should be 'AjaxSucceeded' instead of 'AjaxSucceede'. This is causing the error event to be fired because the server is returning an error response.

⚠️ Common Causes

  • Incorrect or missing data in the request body, or an invalid JSON string.

🚀 How to Resolve This Issue

Method 1: Check Server Response

  1. Step 1: Verify the server response by checking the browser's developer tools or using a tool like Postman to inspect the request and response headers.

Method 2: Validate JSON Data

  1. Step 1: Use a tool like JSONLint to validate the JSON data in your request body and ensure it is correctly formatted.

🎯 Final Words

Always double-check your code, especially when working with JSON data. Additionally, ensure that the server-side endpoint is correctly configured to handle the request and return a successful response.
