x-amazon-apigateway-request-validators and integration not being applied localy

[mac2000]

Description:

I have taken inline_swagger template and modified it to use x-amazon-apigateway-request-validators to not even call my lambda if request is incorrect, but seems like lambda is still invoking in proxy mode

Steps to reproduce the issue:

template.yml

src/index.js

exports.handler = async event => {
    console.log(event)
    return {
        body: 'hello world' + event.id
    }
}

Invokation:

curl http://localhost:3000/get/2

Observed result:

In sam local stdout I do see log containing integration request object with headers, query string and pas parameters

Expected result:

lambda should be called with event containg id only
