gm_create_draft and gm_send_message hang

[pschloss]

Hi,

I've gotten gmailr to work for me in the past, but am running into a problem now where it hangs when I try to send the emails. I'm creating a bunch of pdf receipts that I attach to an email to send to the people receiving the email. Before I fire everything off, I run your example code. Sometimes the example code works, sometimes it hangs on gm_create_draft and and gm_send_message.

gm_auth_configure(path = "~/credentials.json")
gm_auth(email = TRUE)

test_email <-
  gm_mime() %>%
  gm_to("xxxxxxx@umich.edu") %>%
  gm_from("xxxxxxx@gmail.com") %>%
  gm_subject("this is just a gmailr test") %>%
  gm_text_body("Can you hear me now?")

# Verify it looks correct
gm_create_draft(test_email)
#Error in gmailr_POST("drafts", user_id, class = "gmail_draft", query = list(uploadType = "media"),  : 
# Gmail API error: 408

gm_send_message(test_email)

When I get to my loop where I send out the emails, sometimes it will get through several of the recipients and then hang but mostly it is just hanging and not doing anything. This sounds like #126, but I'm not sure.

I have been encountering #126 as well (sending ~50 emails, each with two attachments). Once I got rid of attachments, the issues seem to have gone away (though of course eliminating attachments won't work for everyone). Same version of R and gmailr as you:

For what it's worth, I seem able to get the test email sent out without issue, but like @bomeara mentioned, if I add a PDF attachment to the email it hangs.
