I have checked this but seems different An unhandled exception occurred: Configuration 'production' is not set in the workspace

How can I fix this ?

Answer 1

As far as I can see there is no production configuration in your serve configurations.

  "serve": {
      "builder": "@angular-devkit/build-angular:dev-server",
      "disableHostCheck": true,
      "options": {
        "browserTarget": "Project1:build"
      },
      "configurations": {
        "fr": { "browserTarget": "qwikCollaborator:build:fr" },
        "en": {"browserTarget": "qwikCollaborator:build:en" } 
        }       
    },

As you can see here in your serve block you have fr and en configurations. So you should add production as part of your config

      "configurations": {
        "fr": { "browserTarget": "qwikCollaborator:build:fr" },
        "en": {"browserTarget": "qwikCollaborator:build:en" },
        "production": {"browserTarget": "qwikCollaborator:build:production" } 
        }       

And this should run the production builder
