Description

Hey!

It seems that code that generates ApiPath enum incorrectly tries to deduplicate enum identifiers when paths differs on params. This is as well visible when path has multple params of various level of reusing parameter names.

Reproduction

Small open ap spec

{
  "openapi": "3.0.4",
  "info": { "title": "some api", "version": "1" },
  "servers": [ { "url": "uri:some-api" } ],
  "paths": {
    "/api/block": {
      "get": {
        "summary": "whatever",
        "tags": [ "Block" ],
        "responses": {
          "200": {
            "description": "OK",
            "content": {
              "application/json": { "schema": { "type": "string" } }
            }
          }
        }
      }
    },
    "/api/block/{blockId}": {
      "get": {
        "summary": "whatever",
        "tags": [ "Block" ],
        "parameters": [
          { "name": "blockId", "in": "path", "schema": { "type": "string" } }
        ],
        "responses": {
          "200": {
            "description": "OK",
            "content": {
              "application/json": { "schema": { "type": "string" } }
            }
          }
        }
      }
    }
  },
  "components": {
    "securitySchemes": {
      "awesome": {
        "type": "oauth2",
        "flows": {
          "implicit": {
            "authorizationUrl": "https://example.com/oauth2/authorize",
            "scopes": { "awesome": "Awesome scope" }
          }
        }
      }
    }
  },
  "security": [ { "awesome": [ "awesome" ] } ]
}

command line:

npx openapi-typescript "C:\...\repro.json" -o ./repro.schema.d.ts --make-paths-enum

output:

(...)
export enum ApiPaths {
    GetApiBlock = "/api/block",
    GetApiBlock = "/api/block/:blockId"
}

Expected result

not have same enum member identifiers
