slackr_upload fails with .gif

[tomauer]

I'm on slackr 1.4.2 and am attempting to upload a .gif file to a channel, but it's not working. I used:

httr::with_verbose(slackr_upload(gif_path))

And got:

<- HTTP/1.1 504 Gateway Time-out <- Content-Type: text/html <- Transfer-Encoding: chunked <- Connection: close <- Date: Mon, 06 Nov 2017 10:49:10 GMT <- Last-Modified: Fri, 05 Feb 2016 23:46:05 GMT <- Server: AmazonS3 <- Content-Encoding: gzip <- Vary: Accept-Encoding <- Age: 12974 <- X-Cache: Error from cloudfront <- Via: 1.1 ac094a1c1bf8cbfbb98e93fa2b2431c0.cloudfront.net (CloudFront) <- X-Amz-Cf-Id: lscQ-wJV7XPrivGJzsUsxX9LhoVEG-_zCjt127SB5ko--INRxNBXQA==

I have successfully used slackr() to post to the channel and am able to successfully post a .png file to the channel. I have also tried adding channel explicitly and it doesn't work. Finally, I have also confirmed that the gif exists at the path supplied.

it looks like slack is returning a 504 error which indicates that something on their side is going wrong.

@hrbrmstr any thoughts on something else that it could be?
