#1595 was fixed but it exposed another problem with put-integration

[bradmurray]

(I put this comment in #1595 but it's closed so I wanted to open a new issue)

I installed the develop branch and the code that should be working for put-integration but it is giving me the following error now:

A client error (BadRequestException) occurred when calling the PutIntegration operation: Enumeration value for HttpMethod must be non-empty

It think there is a typo somewhere in that "HttpMethod" should be "httpMethod" because that's the parameter that the CLI is expecting.

If have tried using the regular command-line method as well as the --cli-input-json format and the error is the same.

Here is the debug output:

ClientError: A client error (BadRequestException) occurred when calling the PutIntegration operation: Enumeration value for HttpMethod must be non-empty

A client error (BadRequestException) occurred when calling the PutIntegration operation: Enumeration value for HttpMethod must be non-empty

[bradmurray]

To avoid some confusion, I am passing a variable called HTTPMethod to my Lambda function so that my function can receive the method. That logic works when I put it in via the web.

[quiver]

Same here.
I ran commands like this

$ aws apigateway put-integration --rest-api-id $REST_API_ID --resource-id $RESOURCE --http-method GET --type AWS --uri $LAMBDA_ARN ... A client error (BadRequestException) occurred when calling the PutIntegration operation: Enumeration value for HttpMethod must be non-empty

[kyleknap]

It looks like an issue with botocore's serializer. Also (this will not will not work currently) you will need to specify a --integration-http-method as well when running a put-integration command or you will get the same exception when specifying --type AWS.

[quiver]

@kyleknap thanks for your feedback. It's working fine now.

$ aws apigateway put-integration --rest-api-id $REST_API_ID --resource-id "dummy" --http-method GET --type AWS --uri "arn:aws:apigateway:ap-northeast-1:lambda:path/2015-03-31/functions/arn:aws:lambda:ap-northeast-1:1234:function:GetHelloWorld/invocations" --integration-http-method GET
{
    "httpMethod": "GET",
    "type": "AWS",
    "uri": "arn:aws:apigateway:ap-northeast-1:lambda:path/2015-03-31/functions/arn:aws:lambda:ap-northeast-1:1234:function:GetHelloWorld/invocations",
    "cacheNamespace": "dummy"
}

Awesome. Good to hear.
