If I change the name of a lambda function terraform correctly creates a plan about resources to create/destroy/update, but it won't do anything after running the apply command on the created plan. ### Terraform Version <!--- Run `terraform -v` to show the version, and paste the result between the ``` marks below. If you are not running the latest version of Terraform, please try upgrading because your issue may have already been fixed. --> ``` Terraform v0.11.14 ``` ### Terraform Configuration Files ```hcl resource "aws_api_gateway_rest_api" "TestApi" { name = "TestApi" } resource "aws_api_gateway_resource" "TestApiGWResource" { rest_api_id = "${aws_api_gateway_rest_api.TestApi.id}" parent_id = "${aws_api_gateway_rest_api.TestApi.root_resource_id}" path_part = "{proxy+}" } resource "aws_api_gateway_method" "TestApiGWMethod" { rest_api_id = "${aws_api_gateway_rest_api.TestApi.id}" resource_id = "${aws_api_gateway_resource.TestApiGWResource.id}" http_method = "ANY" authorization = "NONE" } resource "aws_lambda_function" "TestFunction" { function_name = "Test-${terraform.workspace}" filename = "./lambda_payload.zip" source_code_hash = "${base64sha256(file("./lambda_payload.zip"))}" handler = "index.server" runtime = "nodejs10.x" role = "${aws_iam_role.lambda_execute.arn}" } resource "aws_api_gateway_integration" "TestApiGWIntegration" { rest_api_id = "${aws_api_gateway_rest_api.TestApi.id}" resource_id = "${aws_api_gateway_method.TestApiGWMethod.resource_id}" http_method = "${aws_api_gateway_method.TestApiGWMethod.http_method}" integration_http_method = "POST" type = "AWS_PROXY" uri = "${aws_lambda_function.TestFunction.invoke_arn}" } resource "aws_api_gateway_deployment" "TestApiGWDeployment" { depends_on = [ "aws_api_gateway_integration.TestApiGWIntegration"] rest_api_id = "${aws_api_gateway_rest_api.TestApi.id}" stage_name = "${terraform.workspace}" } ``` ### Expected Behavior After changing function name and creating the plan the apply should apply those changes ### Actual Behavior `terraform plan` : Plan: 1 to add, 1 to change, 1 to destroy. `terraform apply out.plan` : Apply complete! Resources: 0 added, 0 changed, 0 destroyed. ### Steps to Reproduce After created all the resources change the value of `function_name` in "aws_lambda_function.TestFunction" `terraform plan -target="aws_api_gateway_deployment.TestApiGWDeployment" -out out.plan` `terraform apply out.plan` or `terraform apply -target="aws_api_gateway_deployment.TestApiGWDeployment" out.plan` ### Additional Context It works if I omit the -target, but I pass target as I want to target a specific deployment:( Trace log: [trace log of apply](https://gist.github.com/steveetm/75ac6481f371126a9340a0df92f3643f) ### References - #20576 (but I don't use count)
