json_unquote函数报错问题

原版本：Version : doris-2.0.10
升级版本：Version : doris-2.1.5-rc02

版本升级后在表中新增了两个字段callercallid和calleecallid，varchar(64)
创建routine load任务，任务中通过json_unquote去除字符型数据中带的双引号

问题：
刚启动时，可以正常写库，但是一段时间后会自动停止消费，routine load任务正常，始终是running，停止消费后网卡流量激增，fe.log日志有报错
Invalid JSON text in argument 1 to function json_unquote: "21d848ea63616c6c00001810@47.100.xx.xx"""
"21d848ea63616c6c00001810@47.100.xx.xx"，是新增的字段对应的值，看日志都是这个新增字段的
其他的之前加的字段，就不报这个问题。

附job：
