Most examples use the same error handler, that error handler logs update.to_dict but doesn't log error traceback. Hiding error traceback is quite bad, removing the error handler entirely causes PTB to use default error logging which does include error traceback.

"""Bot that explains Telegram's "Deep Linking Parameters" functionality.
|
|
|
|
This program is dedicated to the public domain under the CC0 license.
|
|
|
|
This Bot uses the Updater class to handle the bot.
|
|
|
|
First, a few handler functions are defined. Then, those functions are passed to
|
|
the Dispatcher and registered at their respective places.
|
|
Then, the bot is started and runs until we press Ctrl-C on the command line.
|
|
|
|
Usage:
|
|
Deep Linking example. Send /start to get the link.
|
|
Press Ctrl-C on the command line or send a signal to the process to stop the
|
|
bot.
