部署后网页出现An error has occurred. Check your logs or contact the app author for clarification.
我代码里没有使用任何中文字符，deploy的log显示如下

自测了好像跟字符串没关系，我的代码server代码如下，
server <- function(input, output) {
observe({if (input$quit == 1)stopApp()})
rawdata2 <- eventReactive(input$add,{
rawdata <- data.frame(a=input$a,
b=input$b,
)
rawdata
})
output$pre <- renderUI({if(input$add >0) {predict(model,rawdata2(),type = c("prob"))[[2]]}})
}
shinyApp(ui, server)
，本地运行正常，但部署到服务器上就是不能运算，显示An error has occurred. Check your logs or contact the app author for clarification.如果output改成固定的字符串可以部署成功，不知道为啥不能运算

文件编码方式是一致的吗？而且从第一个帖子来看，似乎一个locale是chinese，一个locale是english

InfinityLoop

服务器的是locale是英语，本地Windows下是中文，可能就是这个地方出现的冲突。但老实说这个问题我也偶尔碰到，能不能解决基本都是靠猜和各种尝试。

出现这个错误的时候要到服务器上去看错误日志，在前端是得不到有效信息的。

根据仅有的信息猜测，代码没有中文但是数据有中文，而且是data.frame的colname是中文。

你只给了服务器的信息，windows10，R4.2.1，可以支持原生的UTF-8。但是你本地的windows呢？也是用的R4.2.1的版本吗？
