Failed To Construct File Iterator Getter Is Not Callable In Chrome 60 When Use Json Stringify

Encountering the "Failed to construct 'FileIterator': 'Getter' is not callable" error message when using JSON.stringify in Chrome 60 can be a frustrating roadblock for developers. In this guide, we'll dive into what this error means, why it occurs, and how you can resolve it efficiently.

This error typically occurs when attempting to use JSON.stringify on a File object in the Chrome 60 browser. The issue arises due to the 'FileIterator' being incompatible with the 'Getter' function, leading to the error message. While it may seem daunting at first, there are straightforward steps you can take to overcome this obstacle and get your code back on track.

One of the key reasons you may encounter this error is the attempt to stringify a File object. File objects are complex data structures, and JSON.stringify is not designed to handle them directly. To address this, you need to convert the File object into a format that can be stringified without triggering the error.

A common solution is to extract the required information from the File object and create a new object or array that can be safely stringified. By extracting relevant data such as file name, size, type, and content, you can construct a plain JavaScript object that JSON.stringify can process without issues.

Here's an example of how you can refactor your code to avoid the error:

const file = document.getElementById('file-input').files[0];
const fileInfo = {
  name: file.name,
  size: file.size,
  type: file.type,
  content: 'Content Goes Here', // Replace this with your file content extraction method
};

const jsonString = JSON.stringify(fileInfo);
console.log(jsonString);

By structuring your data in this way, you can effectively stringify the information without running into the 'Failed to construct 'FileIterator'' error. Remember to adjust the content extraction method based on your specific requirements and file handling approach.

Additionally, you can consider implementing error handling mechanisms to manage unexpected scenarios when working with file objects and JSON.stringify. By incorporating try-catch blocks or validating the input data before processing, you can enhance the robustness of your code and provide a smoother experience for users.

In conclusion, encountering the 'Failed to construct 'FileIterator': 'Getter' is not callable' error in Chrome 60 when using JSON.stringify can be a hurdle, but it is one that you can overcome with a better understanding of data handling and serialization techniques. By restructuring your code to accommodate the nuances of file objects and JSON serialization, you can steer clear of this error and ensure your applications perform optimally across different environments.
