Error creating API Gateway Deployment: BadRequestException: No integration defined for method

[Edd Grant]

Hi all,

I am trying to provision some AWS resources, specifically an API Gateway which is connected to a Lambda.

I have a module which provisions the Lambda and returns the lambda function ARN as an output, which I then provide as a parameter to the following API Gateway provisioning code (which is based on the example in the TF docs):

provider "aws" {
  access_key = "${var.access_key}"
  secret_key = "${var.secret_key}"
  region     = "${var.region}"
}

# Variables
variable "myregion" { default = "eu-west-2" }
variable "accountId" { default = "" }
variable "lambdaArn" { default = "" }
variable "stageName" { default = "lab" }

# API Gateway
resource "aws_api_gateway_rest_api" "api" {
  name = "myapi"
}

resource "aws_api_gateway_method" "method" {
  rest_api_id   = "${aws_api_gateway_rest_api.api.id}"
  resource_id   = "${aws_api_gateway_rest_api.api.root_resource_id}"
  http_method   = "GET"
  authorization = "NONE"
}

resource "aws_api_gateway_integration" "integration" {
  rest_api_id             = "${aws_api_gateway_rest_api.api.id}"
  resource_id             = "${aws_api_gateway_rest_api.api.root_resource_id}"
  http_method             = "${aws_api_gateway_method.method.http_method}"
  integration_http_method = "POST"
  type                    = "AWS"
  uri                     = "arn:aws:apigateway:${var.myregion}:lambda:path/2015-03-31/functions/${var.lambdaArn}/invocations"
}

# Lambda
resource "aws_lambda_permission" "apigw_lambda" {
  statement_id  = "AllowExecutionFromAPIGateway"
  action        = "lambda:InvokeFunction"
  function_name = "${var.lambdaArn}"
  principal     = "apigateway.amazonaws.com"
  source_arn    = "arn:aws:execute-api:${var.myregion}:${var.accountId}:${aws_api_gateway_rest_api.api.id}/*/${aws_api_gateway_method.method.http_method}/resourcepath/subresourcepath"
}

resource "aws_api_gateway_deployment" "deployment" {
  rest_api_id = "${aws_api_gateway_rest_api.api.id}"
  stage_name = "${var.stageName}"
}

When I run the above from scratch (i.e. when none of the resources exist) I get the following error:

Error applying plan:

1 error(s) occurred:

* aws_api_gateway_deployment.deployment: Error creating API Gateway Deployment: BadRequestException: No integration defined for method
    status code: 400, request id: 15604135-03f5-11e7-8321-f5a75dc2b0a3

Terraform does not automatically rollback in the face of errors.
Instead, your Terraform state file has been partially updated with
any resources that successfully completed. Please address the error
above and apply again to incrementally change your infrastructure.

If I perform a 2nd TF application it consistently applies successfully, but every time I destroy I then receive the above error upon the first application.

This caused me to wonder if there's a dependency that I need to explicitly declare somewhere, I discovered #7486, which describes a similar pattern (although relating to an aws_api_gateway_integration_response rather than an aws_api_gateway_deployment). I tried manually adding an explicit dependency from the aws_api_gateway_deployment to the aws_api_gateway_integration but this had no effect.

Grateful for any thoughts, including whether this may indeed be a TF bug in which case I will raise it in the issue tracker. I thought I'd check with the community before doing so in case I'm missing something obvious.

Many thanks,

Edd

Hi folks,

Just in case anyone else comes up against this, Radek has provided the solution on StackOverflow.

Cheers,

I am facing the same issue. I tried the solution in the stackoverflow article, it still fails for me.
