Question

I have the following problem I have a pwa with angular and I have a problem when I call the backend, when calling a backend route it does it twice and I can't find the solution

My ngs-config.json

  "index": "/index.html",
  "assetGroups": [
    {
      "name": "app",

          "/index.html",
          "/manifest.webmanifest",
          "/*.css",
          "/*.js",
          "/manifest.json"
        ],
        "urls":[
          "https://cdn.jsdelivr.net/npm/@popperjs/[email protected]/dist/umd/popper.min.js",
          "https://cdn.jsdelivr.net/npm/[email protected]/dist/js/bootstrap.min.js"
        ]
      }
    }, {
