Git - Get My Git Credentials

Hi,

I am unable to call the below API
https://api.fabric.microsoft.com/v1/workspaces/{workspaceid}/git/myGitCredentials

Error:

"errorCode": "FeatureNotAvailable",
  "message": "The feature is not available"

I am able to commit from Power BI Service but not able to call any Git APIs.
It was working for me till yesterday.
From today, I am getting this error.
Am I missing anything here?
Please help
