lua脚本/redis中的打印方法不起作用

我正在尝试执行以下脚本,并得到以下错误。 Redis正在docker中运行

线程“main”org.respon.client.RedisException异常:ERR user_script:1:脚本试图访问不存在的全局变量 “打印”脚本:6f736423f082e141036b833d1f86b5a36a494611,位于 @user_script:1。。

使用redis CLI执行时也会出现相同的错误

Java代码。我正在使用Redison lib连接到Redis并执行脚本。

检查了 Lua print on the same line 线程但是 io.write 也给出了相同的错误。
