"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\"])",
