Thank you! the problem was caused by an unicode string. Changing this line: | "attachment; filename=\"" + os.path.basename(video['title'] + "." + video['format']) + "\"") to this: || "attachment; filename=\"" + str(os.path.basename(video['title']) + "." + video['format']) + "\"")| fixes it.

I hope it is ok when I post the link to stackoverflow, where I already explained the problem. File "/usr/lib/python2.7/dist-packages/twisted/web/http.py", line 1001, in write value = networkString('%s' % (value,)) File "/usr/lib/python2.7/dist-packages/twisted/python/compat.py", line 364, in networkString raise TypeError("Can only pass-through bytes on Python 2")
The source code:
if not isinstance(s, str): raise TypeError("Can only pass-through bytes on Python 2") # Ensure we're limited to ASCII subset: s.decode('ascii')
You could check if what you get here is not a str but unicode. You could change the error message to include the type and value of s
