Hi Klara --

You have code structured like

  out <- tryCatch({
      response = httr::GET(url)
   }, error = function(cond) {
      ... htr::http_status(response)$message

so if GET() fails, response is undefined; I guess this is what happened, the "why" is a mystery but could be as simple as transient internet connectivity.

It seems like you could instead report conditionMessage(cond) in the error function (catching the GET() error), and use httr::stop_for_status() to check for invalid status response from the server.

FWIW your code in utils.R is not consistently indented (sometimes tabs, sometimes spaces); I'd strongly suggest 4 spaces and no tabs. Also message(paste(...)) can usually be represented simply as message(..., including multiline messages.

Hi Bioc team,

I am one of the maintainers the roma package in the devel version.  The package 
is building fine on mac and linux, however I am experience an error on tokay2 
that I have been so far unable to solve. The problem seems to be in receiving 
the responses from the API. which fails in the first vignette with the 
following error message:


Error: processing vignette 'exploring_hogs.Rmd' failed with diagnostics:
object 'response' not found

I have checked the relevant end point and it works as it is suppose to do. 
Furthermore, the same error does not show up in mac and linux servers. Would 
you happen to have any pointers to what might be causing this error?

Thank you in advance,
