R闪亮的网格绘制维恩图

我从闪亮的服务器中发现了类似上面的错误，我的维恩图代码如下

 output$plot12 <- renderPlot({
 venn.plot = venn.diagram(
  x = list(
    data1 = data1,
    data2 = data2
  ),
  main = "Venn Diagram",
  
  filename = NULL,
  na="remove",
  lwd = 2,
  fill = c("orange", "blue"),
  alpha = c(0.5,0.5),
  label.col = "black",
  cex=1.5,
  fontface = "plain",
  cat.col = c("cornflowerblue", "pink"),
  cat.cex = 1.5,
  cat.fontfamily = "serif",
  cat.fontface = "plain",
  cat.dist = c(0.05, 0.05),
  cat.pos = c(-20, 14),
  cat.default.pos = "text",
  scaled = FALSE
)
  grid.newpage()
  grid.draw(venn.plot) })

相同的代码在本地计算机上运行时没有任何错误，但是在将其托管到服务器时显示错误。任何想法如何防止创建venn日志文件
