Hello. I want to use the Rancher API to create a host (an ec2 instance via docker machine). I found this resource `/v1/projects/1a5/machines` that listed my existing machines in this environment. I’m doing a POST via curl and getting a 422 response with some JSON containing an error code and message `“DriverConfigExactlyOneRequired”`. What looks like the same request, via hitting the Create button while browsing the API, works fine and sets up the ec2 instance. I can do an HTTP DELETE on machines via curl but can’t create them. This is my curl command:

```
curl -v -u $RANCHER_ACCESS_KEY:$RANCHER_SECRET_KEY -H 'Accept: application/json' -H 'Content-Type: application/json' --data '{"name": "my-aws-host", "amazonec2config": {"accessKey": "XXXXXXXX”, "secretKey": “XXXXXXXXX”, "ami": "ami-45d8a532", "instanceType": "t2.micro", "region": "eu-west-1", "securityGroup": "rancher-machine", "zone": "a", "vpcId": “xxxxxxx”}}’ http://my.rancher.server:8080/v1/projects/1a5/machines

```

and response body is:

```
{"id":"387965ba-25a1-4431-8924-516a24781842","type":"error","links":{},"actions":{},"status":422,"code":"DriverConfigExactlyOneRequired","message":"DriverConfigExactlyOneRequired","detail":null}

```

Am I missing something from my curl command? Thanks and great work with the API I must say.

Capital “C” in `amaconec2Config`.
