Hi guys, I apologise in advance that this is rather vague, but I'm hoping that someone might be able to point me in the right direction of where I should be looking. I'm getting some strange problems with Dancer2 and the "auto serializer". I have set serializer => 'JSON'; in my app, but under some circumstances it is trying to serialize HTML content, with the subsequent errors that you would expect of such an action. The problems seem to be related to my error handling (using Log::Report). My implementation is currently rather poor and complicated, so I won't go into the details here, but I wondered whether someone can point me to the relevant parts of the Dancer2 code that I should start poking around in (in particular the code which detects whether to serialize the data). I've looked at serialize() in Serializer::Mutuble, but as far as I can tell this function is not being called. Where else should I look? If I remove the aforementioned serializer statement then everything works as expected. Thanks, Andy
