Understanding the Error

Root Cause

Steps to Fix

Identify the Proxy and its Lifecycle

First, identify the origin of the proxy in your code. Determine where the proxy is being created and where it is being revoked. This will give you a clue as to why the proxy is being accessed after revocation.

Review Asynchronous Code

Since proxies can often be involved in asynchronous code, review your async/await patterns. Ensure that you are properly awaiting promises and handling rejections.

Check References

Examine your code for areas where proxies are being passed around. Ensure that you are not inadvertently trying to set properties on a proxy that should have been discarded.
