--csv throws an exception

Hi,

I've added a print(json) before the offending statment. Looks like this redirect isn't handled but the error is caused by trying to index an empty command.

{'commands': [{'command': 'redirect', 'location': 'https://www.flatex.at/?id=18136&windowId=W68492'}]}
{}

PS: I haven't had any luck with PDF download either, the pdfs directory shows up empty. Is this project abandoned?
