部署到shinyapps.io错误：发生错误。检查您的日志或联系应用程序作者以获得说明

Question

我正在尝试部署一个在本地工作正常的Shinyapp。我像这样使用rsconnect：

# I use my actual token and secret
    rsconnect::setAccountInfo(name='myname',
                  token='<TOKEN>',
                  secret='<SECRET>')

然后，我在Rstudio的部署窗格中收到一条确认消息：

Deployment completed: https://myname.shinyapps.io/my_app/

但是，当我尝试访问该链接时，我只看到此消息：

ERROR: An error has occurred. Check your logs or contact the app author for clarification.

我已经从下面的Shiny GUI中粘贴了日志。

我的应用中直接有一个csv文件，可以为应用提供数据。我不确定我看到的问题是否与直接路径有关。

我在申请中没有使用setwd()

这是我的目录结构的屏幕：

在server（）中，我读入数据：

server <- function(input, output) {

  # get data
  ga_data <- read.csv("ga_data.csv", stringsAsFactors = F, header = T)

我不确定csv的读取是否是问题，这可能是一种转移。

以下是Shinyapps GUI中针对该应用程序的日志：
