Typeerror: failed to execute ‘createobjecturl’ on ‘url’: overload resolution failed.

The “TypeError: Failed to execute ‘createObjectURL’ on ‘URL’: Overload resolution failed.” error occurs when the createObjectURL() method is used incorrectly and the browser fails to determine the correct overload to execute.

The createObjectURL() method is used to generate a unique URL for a specified JavaScript object. It is commonly used when working with File or Blob objects.

There are two possible causes for this error:

1. Passing an invalid argument to the createObjectURL() method:

           
             // Example 1: Invalid argument
             const objectURL = URL.createObjectURL(null);
           
         

   In this example, null is not a valid argument for createObjectURL(). Instead, you should pass a File or Blob object.

2. Not properly releasing the object URL:

           
             // Example 2: Not releasing the object URL
             const fileInput = document.getElementById('file-input');
             const file = fileInput.files[0];
             const objectURL = URL.createObjectURL(file);
             // Some code here
             // Forgot to revokeObjectURL
           
         

   In this example, if you forget to call URL.revokeObjectURL(objectURL) after you’ve finished using the object URL, it can lead to memory leaks and cause the error to occur.

To fix this error, make sure you are using the createObjectURL() method with the correct argument, and always remember to release the object URL by calling revokeObjectURL() when you no longer need it:

    
      // Example 3: Proper usage
      const fileInput = document.getElementById('file-input');
      const file = fileInput.files[0];
      const objectURL = URL.createObjectURL(file);
      // Some code here
      URL.revokeObjectURL(objectURL); // Release the object URL
