代码

  "title": "meta",
  "properties": {
    "hospital": {
      "param": "hospital",
      "title": "hospital",

      "extra": "hospital.extra",
      "props": {}
    },

    "blood": {
      "param": "blood",
      "title": "blood",
      "type": "object",
      "properties": {
        "history": {
          "param": "history",
          "title": "history",
          "type": "string",
          "props": {
            "options": [
              {
                "label": "history_0",
                "value": "history_0"
              },
              {
                "label": "history_1",
                "value": "history_1"
              },
              {
                "label": "history_2",
                "value": "history_2"
              }
            ]
          }

        },
        "kou": {
          "param": "kou",
          "title": "kou",
          "type": "string",

          "hidden": "{{!formData.blood.history || ['history_1','history_2'].includes(formData.blood.history) }}"

        }
      }
    }

  }
}

<FormRender
          validateMessages={validateMessages}
          form={form}
          scrollToFirstError
          schema={metaInfo?.Schemas[0]?.JsonSchema}

        />

将上面的json 复制到这里然后 打开控制台 选择或者输入就会有下面提示，

我放到这个里面运行看，没有问题呢，是不是版本锁死了？更新到 2.x 最新版看看

@lhbxs 你要选择下拉框后才会出现这样的问题 TypeError: Cannot read properties of undefined (reading 'history')
