(*models.Error) is not supported by the TextConsumer

[jaredpiedt]

When creating a site using the Netlify terraform provider, I get this error:

&{0 } (*models.Error) is not supported by the TextConsumer, can be resolved by supporting TextUnmarshaler interface

I attempted to create the site via cURL to get more visibility into the API response:

Request

curl -X POST \
  https://api.netlify.com/api/v1/sites \
  -H 'Authorization: Bearer <secret>' \
  -H 'Content-Type: application/json' \
  -d '{
	"name": "test",
	"repo": {
		"provider": "github",
		"repo_path": "jaredpiedt/test",
		"repo_branch": "master"
	}
}'

Response

HTTP/1.1 422 Unprocessable Entity

{
    "errors": {
        "subdomain": [
            "must be unique"
        ]
    }
}

I believe the issue is a result of the response not matching the error schema specified in swagger.yml: https://github.com/netlify/open-api/blob/master/swagger.yml#L2777-L2787
