Error: User Token doesn't adhere to regular expression ^[a-zA-Z0-9\.\-_]+$]

Here is the User Token section from the Swagger.json I am attempting to load.

    "securitySchemes": {
      "User Token": {
        "type": "http",
        "description": "Enter User Token **_only_**",
        "scheme": "bearer",
        "bearerFormat": "JWT"
      }
    }
  },
  "security": [
    {
      "User Token": [ ]
    }
  ]
}
