运行和h2o时出现运行错误（无法分析 URI 查询，赋值后找不到象'train_h2o'

问题遇到的现象和发生背景

运行和h2o时出现运行错误（无法分析 URI 查询，赋值后找不到对象'train_h2o'

用代码块功能插入代码，请勿粘贴截图

library(tidyverse)
library(tidyquant)
library(h2o)
library(lime) #模型解释
library(Rserve)
Rserve() #用来调用Java环境 #用来调用Java环境
Sys.setenv(JAVA_HOME="/Program Files/R/R-4.2.1/library/Java/jdk-19.0.1/")##该语句用来设置环境变量（R-library内）

模型构建和评价

h2o.init()
#h2o.no_progress() #执行可关闭运行结果的进度条

3.2训练集-验证集-测试集####

set.seed(123)
train_h2o <-as.h2o(train)
val_h2o <- as.h2o(val)
y <- "outcome" #就是结局变量
x <- setdiff(names(train_h2o), y) #基于训练集建模

运行结果及报错内容

train_h2o <-as.h2o(train)

我的解答思路和尝试过的方法

用师姐电脑就可以，我已经尝试安装最新JAVA，还是不行。所以希望各位大神帮忙看看。

ERROR: Unexpected HTTP Status code: 500 Server Error (url = http://localhost:54321/3/PostFile?
Error in setdiff(names(train_h2o), y) : 找不到对象'train_h2o'
这2个错误我的解题方向是：
第一个错误是IIS收到请求；但在处理请求过程中出现内部错误。【确认下权限，或者重新安装IIS】
第二个错误是文件引用与包含路径出错(如未启用父路径)【这个可以结合你师姐的环境重新布置】

h2o初始化失败问题解决
