2.424.0 'Invalid request input' on APIGateway.putIntegrationResponse

[gojko]

since release 2.424.0, putIntegrationResponse in API gateway refuses to execute valid requests containing httpMethod, resourceId, restApiId and statusCode

this works with [email protected], but does not work with 2.424.0. (of course, relevant resource IDs need to be set up first)

const aws = require('aws-sdk')
const apig = new aws.APIGateway({region: 'us-west-2'})
apig.putIntegrationResponse({httpMethod: "GET", resourceId: "qlss4p", restApiId: "zrsx0azkpc", statusCode: "200"}).promise()

this is an error thrown from 2.424.0

let resp = apig.putIntegrationResponse({httpMethod: "GET", resourceId: "qlss4p", restApiId: "zrsx0azkpc", statusCode: "200"}).promise().then(console.log).catch(console.error);
undefined

done some more investigation on this, looks like responseTemplates became mandatory in this version. Documentation (https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/APIGateway.html#putIntegrationResponse-property) suggests that this should not be mandatory

@gojko

Thanks for the investigation.

It actually looks like this was due to the change here: #2574

Starting in 2.424.0, the body for this operation was empty, whereas in 2.423.0 and earlier, the body was {}. The service is failing validation on the empty body in the request.

This has been fixed in 2.426.0.

Thanks again for raising this issue.
