Issues with Slack Bot Direct Messages in Lindy Setup

Hi - I've set up a Slack bot in Lindy, but I keep receiving the note that "Lindy has turned off direct messages, so you won't be able to respond to these messages". The Slack bot works fine in public channels, but I'm not able to get it to successfully work in a DM

Hi there, I will be able to take a look at this tomorrow but to get a quicker answer, I would reach out via email since we have a new team member just joined and helping with support

Hi Kha N. - I have another question; unrelated. I just put together another Slack Agent and was testing with a few Slack messages. Lindy then sent 50+ messages and we lost 1,000 credits (of our 5,000 for the month).
1.
Is there a way to ensure that never happens again? I'm not quite sure why it started sending messages non stop. The only way I stopped it was by disabling the agent
2.
Is it possible to recoup the 1,000 credits we just lost in a matter of seconds?

Okay great, thanks - that makes sense

But if you are okay with the conversations being in Slack channels outside of DM's, then you can just have it listen to messages in certain channels (instead of Slackbot)

If you need it to be in DM's only, then you may need to make this Lindy a template, share it with your teammate, and your teammate adds a copy of the agent into their Lindy account

I'm wondering if it's because although you are targeting the entire ADM workspace, you did authenticate through slack through your own account

Yes correct; however I've only been able to get it to work with one specific user
Kha N.

And you want the conversations to be fully private (in DM’s) right?
Kha N.

Ah interesting. That should be working. The Lindy app is added into the Slack workspace?

Here's the agent flow in Lindy:

Kha N. - apologies I have another question. I was able to get it to work for just one user, but we need it to work for all users in the Slack workspace. When I test with my own slack it works great, but here I test with a user in the Slack workspace and it doesn't register receiving the message. We need all individuals in the slack workspace to be able to message Lindy through their Slackbots and receive the answers in their Slackbots

That worked - thank you! 🙂

Ah yes I ran into that too. You’ll need to use Slack Send Direct Message instead. Then it’ll work :)

Kha N. thank you! That makes sense setting it as Slackbot - however, unfortunately now I run into this issue when I test the flow. Message Received and Search Knowledge Base have no problem, however Send Message results in channel_not_found API errors:
