AWS API Gateway multiple methos

Terraform Providers AWS
1

Hi,

I am trying to create API Gateway with two methods PUT and POST using Terraform. Here is my code: Simply I want to create below methods under same API gateway using terraform but getting error Put - /events/updatetags/{object_id} Post - /events/wafacl/add_ipset

Not sure, how to handle stage when creating more than one method using Terraform. Code works for one method.

Error:

│ Error: creating API Gateway Stage (dev): ConflictException: Stage already exists
│ 
│   with module.api_gateway.aws_api_gateway_stage.events_waf_apig_stages,
│   on api_gateway/main.tf line 389, in resource "aws_api_gateway_stage" "events_waf_apig_stages":
│  389: resource "aws_api_gateway_stage" "events_waf_apig_stages" {
