The error message “failed to execute ‘createobjecturl’ on ‘url’: overload resolution failed” usually occurs when there is an issue with the parameters passed to the createObjectURL() method in JavaScript. This method is used to generate a unique URL representing an object in the browser, such as a file or a blob.
The createObjectURL() method expects an object as an argument, usually a File, Blob, or MediaSource object. If the argument is not of the expected type, or if the object is null or undefined, the method will throw the mentioned error.
Here is an example of incorrect usage of the createObjectURL() method that can result in the mentioned error:
var objectURL = URL.createObjectURL("incorrect_argument");
In the above example, the createObjectURL() method is called with a string (“incorrect_argument”) instead of an appropriate object. As a result, the overload resolution fails, and the error is thrown.
To fix this error, you need to ensure that the correct object is passed as an argument to the createObjectURL() method. Here is an example of the correct usage:
var file = new File(["file_content"], "filename.txt", { type: "text/plain" });
var objectURL = URL.createObjectURL(file);
In the corrected example, a File object is created with the desired content, name, and type. Then, this File object is passed to the createObjectURL() method, which successfully generates a unique URL representing the file.
It’s important to note that this error message can also be thrown if the createObjectURL() method is not supported by the browser being used. Therefore, it’s a good practice to check for browser compatibility before using this method.
