Been developing a small add-in that was working fine... now I can't seem to get any local add-in project sideloaded from localhost as the MS guide describes! (https://docs.microsoft.com/en-us/office/dev/add-ins/quickstarts/outlook-quickstart?tabs=yeomangenerator)

Tried npm start(instead of npm run dev-server), output as follows:

The dev server is running on port 3000. Process id: 16396
Sideloading the Office Add-in...
Error: Unable to start debugging.
office-addin-debugging: Unable to sideload the Office Add-in.
Error: Sideload is not supported.

The projects used to show up in the ellipsis menu on web outlook, now they won't load at all.

Tried creating a brand new project, no luck.

checked this very similar thread, no luck. Unable to sideload the Office Add-in when running 'npm start'

...oof

From the document you linked, did you try this part: "Follow the instructions in Sideload Outlook add-ins for testing to sideload the add-in in Outlook.", which links you to docs.microsoft.com/en-us/office/dev/add-ins/outlook/… ? If so, did you get any error trying to sideload? - Outlook Add-ins Team - MSFT
Yes, that was my normal method of sideloading. My app compiles in npm just fine, seems to be accepted by the 'add custom add-in' menu, but does not appear in the ellipsis menu. Script Lab does appear there, installed through appsource but no custom add-ins... - gonsalvg
Sorry this, should have been asked first, but what client are you using to test this? OWA, Mac, Windows? etc. - Outlook Add-ins Team - MSFT
No problem, still having the issue. I am using the web version of outlook to test/sideload, on chrome win10. - gonsalvg
Following up with some people, sideloading from npm run dev-server isn't supported. (it will be coming soon). And you have to install the app manually via the link we provided earlier. After you do this, does it show up in your installed add-ins (under Manage Add-ins?). If it IS there, then there may be some issue inside your manifest, that is preventing it from showing up. If it ISN'T there...it should have given you an error when you tried manually sideload. - Outlook Add-ins Team - MSFT

Installing your test Manifest I see the following:

In the Add-ins button:

In The ellipsis I see:

So it's working for me in OWA, and I also saw similar results in Win32 Desktop Outlook. Are you on a private exchange server? Does your manifest work on an Outlook.com account?
