Error handling response: TypeError: Cannot read properties of undefined (reading 'updatable')

Expected Behavior

When clicking on the icon in the "Last updated" column on chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/options.html#nav=dashboard I expect the update to work.
It does work for some scripts.

Actual Behavior

It's showing the spinning wheel forever and console error:

Error handling response: TypeError: Cannot read properties of undefined (reading 'updatable')
    at chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/extension.js:699:407
    at chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/extension.js:782:341

on url chrome-extension://dhdgffkkebhmkfjojejmpbldmpobfkfo/options.html#url=aHredacted==&nav=dashboard

followed by

Unchecked runtime.lastError: A listener indicated an asynchronous response by returning true, but the message channel closed before a response was received

Specifications

• Chromium: 127 + 128
• TM: 5.1.1
• OS: Win 11

Script

url's are redacted.

// ==UserScript==
// @name		Foo Bar
// @namespace	https://foo.com
// @version		1.0.0
// @description utility buttons for Foo
// @author		Foo
// @updateURL	https://sub.foo.com/bar.js
// @downloadURL	https://sub.foo.com/bar.js
// @supportURL	https://foo.com
// @match		https://bar.com/*
// @grant		none
// ==/UserScript==

I have another script that is basically identical, except that it has a @match for https://*.foo.com/* where the update works, so I know the update works in general.

Found 2 cases where this happens:

• if the update URL returns a 404 error
• if the update URL returns non-JS

Thanks for reporting. Fortunately this issue is already fixed at the BETA version.
