带footer的Reactable本地正常，部署到Posit Connect后异常

问题描述 #

开发的Shiny应用在本地运行正常，但部署到Posit Connect服务器后无法正常工作。经排查，问题出在reactable组件的footer配置项——注释该配置后，服务器上的应用即可恢复正常。

应用代码 #

library(shiny)
library(digest)
library(reactable)

ui <- fluidPage(
  mainPanel(
    reactableOutput("rt")
  )
)

server <- function(input, output) {

  output$rt <- renderReactable({
    rmt <- reactable(mtcars[1:3,],
                     columns = list(
                       mpg = colDef(footer = 'A')
                     ))
    print(digest(rmt))
    print(sessionInfo())
    return(rmt)
  })
}

shinyApp(ui = ui, server = server)

关键观察信息 #

• 本地与服务器生成的reactable对象摘要值完全一致，证明两端生成的对象无差异；
• 该服务器上其他使用相同footer配置的Shiny应用运行正常；
• 本地在RStudio IDE中使用外部浏览器运行应用无异常；
• 部署后页面右键检查元素无法看到表格代码；
• 部署方式为通过Git导入到Posit Connect；
• 使用renv进行环境管理。
