I'm new to AWS API Gateway and got stuck trying to define a mapping templates.
I'd like to map a application/x-www-form-urlencoded POST request to a lambda function I created. I managed to define a route and link it to the function.
But when I tried to create a simple mapping template from the console by clicking "Models" the "Create" with the following definition:
{"body" : $input.json('$')}
it fails with:
it prints "Invalid model specified: Validation Result: warnings : [],
errors : [Invalid model schema specified]
Judging by the [documentation][1] my definition seems right.
On the top of the form it tells me that it's using a JSON Schema syntax wich is different from the documentation linked above.
Is the documentation outdated? Am I submmiting it wrong? How can I solve that?
