What steps have you taken that led to this error?

I got the same error when I docker-compose up the service for several days.

My docker-compose :jack_o_lantern:

version: ‘3.0’

services:

rasa:

image: rasa/rasa:1.10.3-full

ports:

  - 5005:5005
volumes:
  - ./:/app
command:
  - run
  - --enable-api
  - --cors
  - "*"
  - --debug

Same same here: Not using docker, connected to channel facebook and telegram. Everything was working fine untill it started giving me this error message that repeats itself very fast right after the bot is used and then I get a new occurence every few seconds. I have been adding answers with buttons for telegram today.
