rasa: Duplicate messages in Slack channel

Rasa version: 1.1.4

Python version: 3.6.8

Operating system (windows, osx, …): Windows + ngrok

Issue: When I send message to Slack channel, bot answering to me multiple times: Here was an issue with same problem: https://github.com/RasaHQ/rasa/issues/2120

At ngrok logs I see, what User-Agent: Slackbot 1.0 keeps POST me messages with headers:

X-Slack-Retry-Num: 1
X-Slack-Retry-Reason: http_timeout

X-Slack-Retry-Num: 2
X-Slack-Retry-Reason: http_timeout

As I see in slack.py, here is something like workaround for my problem: https://github.com/RasaHQ/rasa/blob/master/rasa/core/channels/slack.py#L148

I’ve tried to modify credentials.yml:

slack:
  slack_token: "xoxb-****"
  errors_ignore_retry: "http_timeout"

But it doesn’t work. (same problem on production server with docker)

Summarizing:

Slack duplicate messages to bot with reason of http_timeout even when no custom_actions executed (just utter from domain.yml)
Bot replies to every retry attempt
I can’t bypass http_timeout with errors_ignore_retry

Could you advice please?

Hi, I’m facing very similar issue. After checking the source code, there is code for handle retry case but I spot this: https://github.com/RasaHQ/rasa/blob/e002d095134d52afbd4474a77738739957263db6/rasa/core/channels/slack.py#L256

retry_reason = request.headers.get("HTTP_X_SLACK_RETRY_REASON")
retry_count = request.headers.get("HTTP_X_SLACK_RETRY_NUM")

When I read the request from slack, it turn out that slack sending the request with different headers (“x-slack-retry-reason” and “x-slack-retry-num”) so I changed the code to:

retry_reason = request.headers.get("x-slack-retry-reason")
retry_count = request.headers.get("x-slack-retry-num")

And now it is working as expected. I’m not sure if we can set this text as variable instead of hardcoded string?

However, my form seems to stay active and each new message send to the bot will trigger the form.

Why is there more user input happening without any response from the bot? IMO this is probably a UX problem – if you have an action that is going to take a long time, you should let the user know (e.g. “Sure, let me get that for you, this might take a few seconds…”
