Change to aws_api_gateway_integration destroys all aws_api_gateway_integration_response resources

[irnc]

Terraform Version

v0.7.8

Affected Resource(s)

• aws_api_gateway_integration
• aws_api_gateway_integration_response

Expected Behavior

Change to aws_api_gateway_integration request_templates does not destroy aws_api_gateway_integration_response resources on the same method.

Actual Behavior

Change to aws_api_gateway_integration request_templates destroys all aws_api_gateway_integration_response resources on the same method.

Steps to Reproduce

1. terraform apply

We just ran into this behavior while deploying to production. Fortunately it can be worked around by running terraform apply twice before creating a deployment but it's still annoying and unexpected.

Terraform v0.8.5
I came across this bug today. Modifying aws_api_gateway_integration.request_templates results in the related api_integration_response being deleted. The deletion is not shown in a plan though:

➜  terraform git:(master) ✗ terraform apply plan
module.clickstream_api.aws_api_gateway_integration.api_integration: Modifying...
  request_templates.application/json: ...omitted...
module.clickstream_api.aws_api_gateway_integration.api_integration: Modifications complete

Apply complete! Resources: 0 added, 1 changed, 0 destroyed.

Right after that command I don't see the integration response in AWS web-interface; related endpoints start to fail. Rerunning terraform plan and terraform apply solves the problem:

+ module.clickstream_api.aws_api_gateway_integration_response.api_integration_response
    http_method:                                                            "POST"
    resource_id:                                                            "4o74kk"
    response_parameters.%:                                                  "1"
    response_parameters.method.response.header.Access-Control-Allow-Origin: "'*'"
    response_templates.%:                                                   "1"
    response_templates.application/json:                                    "{\n  \"response\": $input.body\n}\n"
    rest_api_id:                                                            "9i8sauxw3k"
    status_code:                                                            "200"


Plan: 1 to add, 0 to change, 0 to destroy.

same problem here :(
terraform 0.8.7

[naikajah]

Terraform v8.7
I accidently got into this problem with api_gateway_integration_response configuration getting destroyed everytime terraform sees a change in api_gateway_integration configuration.

The other issue which got me into the above bug is a bit odd and relates to using MOCK endpoint. The URI parameter used for api_gateway_integration even though the value is same in every plan/apply, terraform sees it as a change. The tfstate file is getting updated with the same value everytime.
