Runtime Error

What This Error Means

This error occurs when attempting to access a property on an object that has been replaced by a proxy, which has since been revoked. This can happen when using proxy traps to intercept property access and then attempting to access the original property after the proxy has been destroyed.

Why It Happens

This error typically happens when a proxy is created to intercept property access, but the proxy is not properly managed. For example, if a proxy is created and then immediately replaced with the original object, attempting to access a property on the original object will result in this error.

How to Fix It

1. 1To fix this error, ensure that the proxy is properly managed and not replaced with the original object. Check for any unnecessary proxy creations or replacements. You can also use the `isRevoked` method to check if a proxy has been revoked before attempting to access its properties.

Example Code Solution

const originalObject = { foo: 'bar' };
const proxy = new Proxy(originalObject, {
  get(target, prop) {
    return target[prop];
  }
});
proxy.foo = null;

originalObject is replaced with a new object
originalObject = {};
console.log(proxy.foo);
