Hi, I'm not sure if this is a duplicate, but I decided to open a new one.

Steps to reproduce

1. Get necessary tokens, set up test payment methods (I used stripe test)

2. Start the payment example bot

3. Execute the /shipping command in telegram, in the dialog with the bot

Expected behaviour

The bot should accept the shipment details put in by the user.

Actual behaviour

The bot throws an exception, and doesn't handle the data in the user input in any way.

Configuration

Operating System:
Arch linux

Version of Python, python-telegram-bot & dependencies:
python-telegram-bot 12.0.0b1 (cloned from master commit 26ce9bb)
certifi 2018.11.29
future 0.17.1
Python 3.7.2 (default, Jan 10 2019, 23:51:51) [GCC 8.2.1 20181127]
