The problem here is that your projects are misconfigured in the angular.json. You have two projects in the same directory as the root is configured the same, as such the CLI cannot determine which project you intend to use.

     "blog-admin": {
            "projectType": "application",
            "root": "",
            "sourceRoot": "src",
    },
    "blog-admin-e2e": {
         "root": "",
         "sourceRoot": "",
