Vercel Chrome Extension Causes feedback.html Error

Feedback

Hello,
I installed the fixed version of the Vercel Google Chrome extension on another computer but still encountered the same issue. Although the occurrence rate is very low, once triggered, it prevents the Toolbar from loading.

During testing, I found that this issue appears to be related to get-tab-headers-response, occurring in the following code segment:

if ("get-tab-headers-response" === o.data.type && o.origin === window.origin) {
    window.removeEventListener("message", n);
    var s = null === (i = Object.entries(o.data.headers).find((function(e) {
        return R(a(e, 1)[0], t, r)
    }))) || void 0 === i ? void 0 : i[1];
    e(s);
}

The error occurs when o.data.headers is undefined, causing the Toolbar to fail to load properly.

Observations from Testing

  • Although this issue occurs rarely, once triggered, reloading the page will consistently reproduce it. The only way to resolve it is by clearing the cache.
  • The issue appears to be related to tab-switching behavior, such as:
    • After successfully loading the Toolbar, switching to another tab and then returning to reload the page may trigger the error.
    • In some cases (e.g., after switching tabs and waiting for some time), refreshing the page makes the issue more likely to occur.

I hope this information helps with further troubleshooting. Thank you!
