Slack Error Channel ID

I have a table of tasks with an Owner and a Manager. I want the Manager notified (preferably via slack) when the task is completed by the Owner. I have set up the automation but get a notification that the channelID cannot be found.

Hey @Morgan_Eliason , thanks for reaching out. We’re unable to see the full automation setup from the screenshot shared. However, this is a common error when the channel name has a typo.
I’d recommend double-checking the parameter channelOrEmail

channelOrEmail: The channel to send this message, or the email address of the user if sending directly. For example, “general” or “person@email.com”. To send to a private channel or multi-DM, use the channel ID (from the “About” popup) instead of the name. Channel ID should be specified in upper case while channel name should be specified in lower case.

You can find more info here: Slack Pack, extend Coda with Slack - Coda.

Found that there is an Channel ID error when there are multiple people tagged in a cell. This resolved the issue for some rows, but the automation is still not happening for all rows.
