It would be nice if that were the problem, however substituting: `my $writer = $respond->(200, [ 'Content-Disposition' => 'attachment; filename="data.csv"' ] + );` [download] with `my $writer = $respond->([200, [ 'Content-Disposition' => 'attachment; filename="data.csv"' ] +] );` [download] or even just `my $writer = $respond->([200, ['Content-Type' => 'text']] );` [download] still doesn't work (same error). I wouldn't be suprised to have it be something so simple. Unfortunately, I've only found the one example in the documentation and it's a little sparse (IMO).	[reply] [d/l] [select]

Yes it would have :) I see by override\|streaming&i=1&n=1&C=0 that dancer doesn't test interface, so its not surprising the documented examples don't work -- report bug upstream, http://www.perldancer.org/irc is usually occupied Also, you could try searching for examples on github, its not unheard of :)	[reply]

Found it! The problem was that, even though I'm over-riding things so that it is sending back the results of the loop rather than an actual file-system file, the file-system file has to exist and dancer needs to be able to access it. Rather than dropping a helpful error message along the lines of "file does not exist" it just gacked. We're happy now...	[reply]

Apparently you can also use `\'fake file'` with the contents being 'fake file' :)	[reply] [d/l]
