How to fix Chrome s sendRequest error TypeError Converting circular structure to JSON

Question

With the help of code can you tell me how to fix Chrome's "sendRequest" error: TypeError: Converting circular structure to JSON?

Answer 1

This error occurs in JavaScript when an object contains a circular reference and is passed to JSON.stringify(). This method cannot handle circular structures, where an object refers back to itself directly or indirectly.

How to fix this issue:

1.Manual Circular Reference Handling: One solution is to modify the object before calling JSON.stringify(). You can manually detect and exclude circular references. Here's a simple function to handle it:

function stringify(obj) {

  let cache = [];

  let str = JSON.stringify(obj, function(key, value) {

    if (typeof value === "object" && value !== null) {

      if (cache.indexOf(value) !== -1) {

        return; // Circular reference found, discard key

      }

      cache.push(value); // Store value in our collection

    }

    return value;

  });

  cache = null; // Reset the cache

  return str;

}

2.Using Libraries: Libraries like JSONC can convert circular structures to JSON.
