sourceControls resource Error (same error in Azure Portal Deployment Center as well)

[vllama]

When browsing to the sourcecontrols node on a newly created appService web app, it returns the following error: (on an older webApp I created, it works fine) This error is also visible in devtools when browsing Deployment Center in the portal. I assume it calls the same API

This seems to happen when you create a webApp from a template exported from the resource manager.

this line : "scmType": "ExternalGit", seems to be causing the issue

"siteConfig": {
...
    "scmType": "ExternalGit",
... 
}

The error seems to be coming from the server. Since this tool is just a client that returns the error from server I think the best place to get support for this is
