表單配置，創(chuàng)建表單，設置級聯(lián)選擇組件后，然后在系統(tǒng)設置這邊，設置參數(shù)保存時，級聯(lián)選擇組件值JSON解析錯誤

接口：/api/admin/system/config/save/form

{

   "code": 500,

   "message": "JSON parse error: Cannot deserialize instance of `java.lang.String` out of START_ARRAY token; nested exception is com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of `java.lang.String` out of START_ARRAY token\n at [Source: (PushbackInputStream); line: 1, column: 416] (through reference chain: com.zbkj.common.request.SystemFormCheckRequest[\"fields\"]->java.util.ArrayList[5]->com.zbkj.common.request.SystemFormItemCheckRequest[\"value\"])",

   "data": null

}

這個要怎么解決？
