When I set topic for slack channel, it does not receive dynamic ID
Click on the engine and expression inside.
You have to add the dynamic channel name created in another node (using a function, function item or set node) .
Could you please also share what message it displays if you however over the error-icon.
Hi, I knew why
I use “Access token”, this just use for bot, and bot can not edit channel topic
Then I use “Auth token”, this use for user. And now it seems alright.
Great to hear that it works now!
