Uncaught TypeError: Failed to execute ‘createObjectURL’ on ‘URL’: Overload resolution failed.

When you encounter the “Uncaught TypeError: Failed to execute ‘createObjectURL’ on ‘URL’: Overload resolution failed” error message, it usually means there’s an issue with the usage of the createObjectURL() method in your JavaScript code.

Possible Causes:

  • Incorrect parameters: The createObjectURL() method accepts an object as its parameter, such as a Blob or File object. If you pass an invalid or unsupported object, this error may occur.
  • Browser compatibility: The createObjectURL() method is not supported in all browsers. Make sure you check the browser compatibility before using this method.
  • Expected different parameters: This error can also occur if you expect different parameters while using the method. You need to ensure that you’re passing the correct data type and format.

Examples:

Example 1: Incorrect Parameter

// Creating a createObjectURL with an incorrect parameter
const data = "Some text data";
const url = URL.createObjectURL(data); // Error: Failed to execute 'createObjectURL' on 'URL': Overload resolution failed.

Example 2: Browser Compatibility

// Check browser support before using createObjectURL
if (window.URL && typeof window.URL.createObjectURL === 'function') {
    const file = new File(["Hello world"], "example.txt", {type: "text/plain"});
    const url = URL.createObjectURL(file);
} else {
    console.log("createObjectURL is not supported in this browser.");
}

Example 3: Expected Different Parameters

// Creating a createObjectURL with expected parameters
const blob = new Blob([data], {type: "text/plain"});
const url = URL.createObjectURL(blob);

By carefully reviewing your code and ensuring the correct usage of parameters and browser support, you should be able to resolve the “Uncaught TypeError: Failed to execute ‘createObjectURL’ on ‘URL’: Overload resolution failed” error.
