[Terminal Chat Setup] App link like ms-terminal-can://... doesn't launch Terminal

[dmealo]

Windows Terminal version

1.23.3091.0, 1.23.3101.0

Windows build number

10.0.22631.0

Other Software

No response

Steps to reproduce

1. Launch Settings
2. Navigate to Terminal Chat (Experimental)
3. Expand GitHub Copilot under Service Providers
4. Click Authenticate via GitHub
5. Authenticate and approve access to GitHub account in browser
6. Click "Open Terminal Canary" in resulting browser modal dialog

Expected Behavior

Windows Terminal Canary should launch and receive the auth token from GitHub to complete GitHub Copilot setup for Terminal Chat.

Actual Behavior

Windows Terminal Canary does not launch. This does not work from the default browser (Chrome) nor from Edge.

[radrad]

The same for me. It looks like Windows Terminal Canary is not registered to handle ms-terminal-can://...

I am on windows 10

Thanks for filing! Could you share what's in the OS's Settings app under "Apps" > "Default apps" > "Choose defaults by link type" /?
It may be different on windows 10, but it should exist though.

We're expecting it to look something like this:

I have the settings just like it shows in the screenshot:

However, the terminal does not get launched.

[Zheke32174]

I am having the same issue. I can not find any solution online. I am on windows 11 24h2. I find this especially confusing because GH auth redirects back to the terminal from the browser but copilot does not.

[jvcosmo]

I'm unable to login to use Github Copilot because of that problem. Even registered, the browser doesn't redirect to terminal canary.

[dmealo]

My settings are as @tino-github ’s, please do not close.

[lly-c232733]

same issue for me. cannot use copilot cli because of this

[carlos-zamora]

We're struggling to get a repro. Can one of you with a repro provide a screenshot of the resulting error /?

[tino-github]

A bit unexpected, this question as there is no error. The issue is that a link such a shown below does not trigger MS Terminal Canary to open.

ms-terminal-can://github-auth?code=123456789&state=abcdef

[lly-c232733]

tino describes the exact same problem as I am having.

I try to follow the following instructions: https://devblogs.microsoft.com/commandline/github-copilot-in-windows-terminal/

I am able to complete steps 1-3 of the setup. but after logging it github and authorizing windows terminal access I am shown this webpage:

I am not automatically re-directed so I try clicking the hyperlink called 'this setup page' which is a url like this: ms-terminal-can://github-auth?code=xxxxxxxxxxxxxxxxxxxxx&state=xxxxxxxxxxxxxxxxxxxxxxx

clicking the link does nothing.

I check in windows the default app to open this link, and it seems correct, but will not work.

Is the windows registry incomplete?

Shouldn't there be subfolders '/shell/open/command' with a path to executable plus arguments ???

[PankajBhojwani]

For everyone facing this issue - are you launching Windows Terminal Canary elevated/as administrator? If so we have a temporary fix - launch Canary unelevated, complete the whole Github Copilot auth flow, and then switch back to elevated - your credentials will already be stored and you will be able to use Terminal Chat.

If anyone is experiencing this issue while not running elevated/as administrator, please let us know!

[lly-c232733]

I am not running it as admin

[dmealo]

@PankajBhojwani, that worked for me at least! Thanks!

[tino-github]

@PankajBhojwani, thanks for the workaround! It worked for me.

[carlos-zamora]

I am not running it as admin

@lly-c232733 Hmm... A few questions from the team:

• Do you have UAC on?
• Can you share a copy of your settings.json file?

Any update?

[lly-c232733]

I just tried today and it worked. I'm not sure what changed.
