'RDCOMClient package suddenly gives me: No support for InterfaceSupportsErrorInfo

I've been using the RDCOMClient packge in R for over a year now without a problem.

Now suddenly it's giving me an error:

<checkErrorInfo> 80070057 
No support for InterfaceSupportsErrorInfo
checkErrorInfo -2147024809
Error: The parameter is incorrect.

Here is my code (I've cleaned the code due to privacy):

library(RDCOMClient)
library(lubridate)


rmarkdown::render("/report.Rmd", encoding = "UTF-8")

OutApp <- COMCreate("Outlook.Application")
outMail = OutApp$CreateItem(0)


text <- paste("Attached is the report")
path_to_attachment <- "W:\\Rwd\\report\\report_this_month\\report.pdf"



outMail[["to"]] = "[email protected]"
outMail[["subject"]] = "Monthly report"
outMail[["htmlbody"]] = text
outMail[["attachments"]]$Add(path_to_attachment)

outMail$Send()

rm(OutApp, outMail)

I have few other scripts that I schedule to send emails. One of them uses the blastula package (also sends email through Outlook) and I have no problem there.

Any idea why I'm getting this error?

remailrdcomclient

I came across this error and was clueless for a while, but in my case it ended up being a matter of my attachment filepath being wrong.

If I were you I would try to first comment out the line outMail[["attachments"]]$Add(path_to_attachment) and see if things work as expected.
