Azure Media Service -Create Live Event API

“code”: “InvalidResource”,

    "message": "The resource definition is invalid.

My Azure environment is a US Government tenant. My request is as follows

An Invalid Resource error means your request is not well formed. It looks like you need to fill in for your own parameters. “:subscriptionId” for example should be the subscription ID you created in your Azure environment. Every parameter starting with “:” should be updated with your environment’s values.
