## Describe the bug

When deploying a new QNA maker service via az cli, using an ARM template, however I am unable to perform any actions - either via the qnamaker.ai portal or programatically via the rest api.

the template is as follows

`

The process finish successfully and when I try to connect to the QnaMaker.ai or the api I get this error

> GET https://westus.api.cognitive.microsoft.com/qnamaker/v4.0/endpointkeys HTTP/1.1
Host: westus.api.cognitive.microsoft.com

}
}

## To Reproduce:

The command is
- `az deployment group create --resource-group {} --template-file {} --debug`

with the resource group name and the json file.

Then I try to access the qna maker with the API and get the above error.

## Expected Behavior

After the creation of all the resources, I should be able to interact with the qnamaker.ai or with the qna API.

## Environment Summary
```
Windows-10-10.0.19041-SP0
