Uncaught (in promise) Error: Could not establish connection. Receiving end does not exist.

Getting this error while creating a chrome extension "Uncaught (in promise) Error: Could not establish connection. Receiving end does not exist."

That's basically mv3 for you, I know it's not a very useful answer, but that's what comes to mind when I see it.

This error has always been around and it's often caused by an architectural deficiency in Chrome - the lack of automatic re-injection of the content scripts in the currently open tabs after the extension is updated/installed/reloaded like Firefox does it. The solution for Chrome is to inject the scripts explicitly in chrome.runtime.onInstalled, see https://stackoverflow.com/q/10994324.

I think that makes sense, I had a really bad day yesterday. I have an extension that calls the underlying service worker every second in some cases so that could explain why am I seeing it while developing and restarting the extension.
