How do I debug aws api gateway lambdas aws apigateway 5xxerror

Question

I am working with API Gateway that has lambda function and when I'm calling API Gateway using AWS generated SDK from the API gateway, Here on my API Gateway Dashboard I get this error, "AWS/apiGateway 5XXError". How can I debug it?

Answer 1

First, create an IAM role with the following policy attached to allow API Gateway to push the logs.

{

    "Version": "2012-10-17",

    "Statement": [

        {

            "Effect": "Allow",

            "Action": [

                "logs:CreateLogGroup",

                "logs:CreateLogStream",

                "logs:DescribeLogGroups",

                "logs:DescribeLogStreams",

                "logs:PutLogEvents",

                "logs:GetLogEvents",

                "logs:FilterLogEvents"

            ],

            "Resource": "*"

        }

    ]

}

Now On the API gateway console Enter the ARN of the API Gateway-CloudWatch logging role and save it. Once done go to CloudWatch setting and enable Cloudwatch Logs, Set Log Level to INFO and Select Log full request/response data.

Once done redeploy your API to the stage and then make a request and check for the logs.

And then give the caller's IAM role access. 

Credentials: 'arn:aws:iam::*:user/*'
