Hi all,

Sometime my package got "Empty reply from server" error when I using httr package.
The pseudo-code I used to handle error is like this:

APIurl <- "https://www.ebi.ac.uk/proteins/api/features?offset=0&size=-1&reviewed=true&types=DNA_BIND%2CMOTIF%2CDOMAIN&taxid=9606&accession=K7PPA8%2CP04637%2CQ53GA5%2CH2EHT1%2CA0A087X1Q1%2CA0A087WXZ1%2CA0A087WT22"
response <- GET(featureURL)
if(!http_error(response)){    content <- httr::content(response)}
}, error=function(e){

But I did not get the error handled. What is the correct way to handle the curl 52 error?
Thank you for your help.

Yours Sincerely,

Jianhong Ou
