[Twisted-Python] treq POST abborting with: err: ('Could not adapt', '{"....", "..."} <InterfaceClass twisted.web.iweb.IBodyProducer>)

[steven meiers]

thanks for the quick replys guys, you were right. a .encode('utf-8')
helps.

actually the json.dumps part in the code is wrong.
it has to be: 
 somepage = yield treq.post(target_url, body.encode('utf-8'),
headers=headers, cookies=cookies )
