Thanks for your example. I had originally misunderstood your post in that it seemed that POST works but GET fails. But from reading your code, it seems to be the other way around.

I found Dancer diagnostics to be horrible and do not trust its log anymore. Have you made sure that warnings do not get treated as fatal by Dancer? Maybe trace that the POST handler actually gets invoked by doing print-debugging.

If all else fails, redirect to a GET handler from your POST handler:

post '/test/csv' => sub {
    return redirect '/test/csv';
};
