Describe the bug

Unable to add/modify GraphQL API with Lambda authorisation using headless.

Expected behavior

We should be able to add/modify GraphQL API with Lambda authorisation using headless.

Reproduction steps

1. amplify init
2. amplify add function (Give function name as "hello")
3. Create a JSON which will have configuration for the GraphQL API. You may refer the below example

myAddApiRequest.json

{
    "version": 1,
    "serviceConfiguration": {
        "serviceName": "AppSync",
        "apiName": "newHeadlessApi",
        "transformSchema": "type Salary @model @auth(rules: [{ allow: custom }]) {\r\n  id: ID!\r\n  wage: Int\r\n  currency: String\r\n}",
        "defaultAuthType": {
            "mode": "AWS_LAMBDA",
            "lambdaFunction": "hello"
        }
    }
} 

4. Perform command cat myAddApiRequest.json | jq -c | amplify add api --headless
