I was able to connect rasa to slack via ngrok. Now, when im trying to interact with the bot from slack it is giving an error. The settings of rasa are here and error is given below image|690x387
error:
slack.errors.SlackApiError: The request to the Slack API failed. The server responded with: {‘ok’: False, ‘error’: ‘missing_scope’, ‘needed’: ‘chat:write:user’, ‘provided’: ‘incoming-webhook,im:history,channels:history,groups:history,mpim:history’}
Any clue ? how to solve this issue.
