Slack bot integration user_not_found

[mforbak]

Hello,

I am trying to integrate Danswer with our Slack instance, and I have an app created, as mentioned in the docs, and I have created a channel and invited a bot into that.

After indexing ~16K documents I can now see the connector failed with Error MSG:

The request to the Slack API failed.
(url: https://www.slack.com/api/users.info)
The server responded with: {'ok': False, 'error': 'user_not_found'}

Any idea how to skip the problematic dokument? Run Update doesn't help, cause it trying to index the failed document again.

We have this issue as well, it seems to relate to a user who appears like this is our chat history now:

"Private user info" ?

They have been deleted, but other deleted users don't appear like this one so perhaps a particular process has occurred for this user that now has this unique state.

perhaps we could modify this:

https://github.com/danswer-ai/danswer/blob/main/backend/danswer/connectors/slack/utils.py#L95

from

elif e.response["error"] in ["already_reacted", "no_reaction"]:

to

elif e.response["error"] in ["already_reacted", "no_reaction", "user_not_found"]:

so it ignores those errors returned by slack api?

@psblah thank you! After changing the code it is working :)
