Hey everyone,

 I am using nx: "20.2.1", angular "19.0.4", with "executor": "@nx/angular:dev-server", as executor arcgis: "4.31.6", and "skipLibCheck": "true". Any help would be appreciated 🙂

I've fixed it by updating my project.json serve config to not prebundle.

"serve": {
      "executor": "@nx/angular:dev-server",
      "options": {
        "host": "127.0.0.1",
        "prebundle": false
      },
      "configurations": {
        "production": {
          "buildTarget": "frontend:build:production"
        },
        "development": {
          "buildTarget": "frontend:build:development"
        }
      },
      "defaultConfiguration": "development"
    },
