我去掉了代码中所有的中文字符，甚至注释中的也一并去掉了。部署前也运行了options(encoding = "UTF-8")，但是运行后总是出现：

> warnings()
警告信息：
1: In readLines(certificateFile, warn = FALSE) :
  invalid input found on input connection 'E:/R library/rsconnect/cert/cacert.pem'
2: In readLines(certificateFile, warn = FALSE) :
  invalid input found on input connection 'E:/R library/rsconnect/cert/cacert.pem'
Warning message:
In readLines(certificateFile, warn = FALSE) :
  invalid input found on input connection 'E:/R library/rsconnect/cert/cacert.pem'

而在我运行library(rsconnect)后没有警告出现了（这行代码在server.R中也有），deploy过程中也没有报错，可是最后打开的网站就顶部写着：

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

除此之外没有别的报错了。请问有一些解决方案或者是提示吗？
