Slack Node Can't fetch channel names

Questions

Hello!
I’m trying to send a slack message with my N8N Automation.
The node can’t fetch channel names despite I give the app the appropriate access.

I double checked I’m using the appropriate Access Token and reinstalled my app.
What should I try? Thanks.

Hi

Thanks for posting here and welcome to the community! :cupcake:

Which kind of credentials have you set up? (Slack Access Token or OAuth2?)

If it’s a lot of channels it can take a while, I noticed that too sometimes. But it works if you refresh the node (click the canvas, save and return back to the node).

Access Token.
I don’t have a lot of slack channels.
I think I tried refreshing the node multiple times but it’s not working.

Up please.

Do you still see the same scope error in the response?
