Review Comment:

``` r
arrow::read_ipc_stream("https://httpbin.org/status/404";)
#> Warning in url(file, open = "rb"): cannot open URL
'https://httpbin.org/status/
#> 404': HTTP status was '404 Not Found'
#> Error in url(file, open = "rb"): cannot open the connection to
'https://httpbin.org/status/404'
