Synapse Vs code Plugin Unable to Sign in

priyankabishnoi — Fri, 17 May 2024 22:37:23 GMT

I have intalled Visual Studio code and Synapse Vs code extension, when i go to command pallet to type Synapse:Sign in then after all the configuration a pop up window opens up to sign in to Fabric. The problem is that the url which it shows when i click on Sign in is pointing to localhost and some random port. I believe the Sign in button should point to Microsoft fabric lgin url. What do i need to do to acheive that. Also i see that some fabric kerels are created. How do i select them?

Hi @priyankabishnoi
Thanks for using Fabric Community.
Synapse VS Code extension uses Microsoft Authentication Library (MSAL) to acquire token for users. When user clicks the 'Sign in' command, extension will initiate the MSAL process by listening on a localhost:port, and opens the system browser, where the user supplies the AAD credentials. Once user finishes login authorization in the window, MSAL server will send the auth token back to localhost:port, extension is listening on it so we can receive the response and get the token.
This is by design.Could you login to the extension? Can you please provide me the screenshot and explain what is happening?
And you should choose the Synapse Kernel in the notebook before running.

Hope this helps. Please let me know if you have any further questions.

Also on re-reading your comment i double checked my environment and i saw msal was not installed. So i installed msal in my venv. But I see the same issue. Login screen keeps spinning and asks me for no user and password

Not sure if you saw the details i posted as priyankabis. The login page is not opening. Is there a way to check what is missing. I tried connecting using msal directly in one of the python notebooks. I found that the redirectiin ur is not set to localhost. But why Synapse Sign in is not showing that problem. Why dont I get the userId and password prompt on Synase Sign in

Hi @mtucker
This issue has been resolved. The issue was with the VS code settings with respect to proxy and certificates.

Hi All,

I resolved the issue . There are some proxy and certificate issues in VS code which needs to be updated

Go to Settings-> Applications

Make Sure the following

Proxy Strict SSL is unchecked
Proxy Support is Off
System Certificates unchecked

In Settings -> Security-> Workspace

Trust:Empty Window is unchecked

Hope this hekps

I attempted this solution with no success. Any ideas what else can be done?

Check is popup blockers are installed. Because when you sign in then the browser will open a window

Yeah, that was it. One of my adblocks. Seems obvious in hindsight I suppose. I've given myself a facepalm. Thank you so very much!

After doing this I went to settings and searche for @ext:vscode.microsoft-authentication; and select "classic" on the implementation and it worked.
