debug popup while using chrome ext apis

[darix989]

Hello,
I wonder how I am supposed to debug and inspect the popup component of the chrome extension.
I am asking because if I try to run the app at http://localhost:PORT/popup.html I will get errors for any attempt to use chrome apis.
See my console output below for more details.
Also, I can see it complains about a failed attempt to load a js chunk (which does not exist in my folder), I am not sure if this is related.

Can someone help, please?
Thanks in advance!

FYI: I was not able to use the chrome api in this way, but then I discovered that by right clicking the icon of your extension, you can click on "Inspect popup", which is enough for what I need!
