rules: {
      name: [
        { required: true, message: "", trigger: "blur" },
      ],
},

this is the layout code and the rules code in data, but when I fill in the data on the page, the button always prompts "Please enter the department name", and the console reports async-validator: ["name is required"]

the same updata box can be used normally. I don"t know what"s wrong. I haven"t found it for a long time. Thank you, boss
