Timeout error on rasa shell

Rasa version: 1.3.9

Python version: 3.6

Issue: https://forum.rasa.com/t/timeout-error-on-rasa-shell/19638

Error can be reproduced on examples/restaurantbot. Add a time.sleep(15) to any action and run the bot.

Error (including full traceback):

Command or request that led to error:

rasa shell

I’m having the same issue. We use rasa shell in development in order to have a lighter environment (just two containers needed, rasa-worker and the actions app). When we load a new model the API call to PUT /model takes more than 10 seconds, and the console crashes. Can you please add a config variable that overrides DEFAULT_STREAM_READING_TIMEOUT_IN_SECONDS? Thanks!

Got a similar problem when I start a bot in rest-mode with rasa==1.9.5

My action calls another REST-service and does several retries when it fails. This may take some. I could of course change this, but it would be way more convenient to have a configurable timeout. And also a possibility to inform the user somehow, see https://github.com/RasaHQ/rasa/issues/5588
