An error occured when connecting script with Slack message action

Hi,

I’m creating an automation which:

  • triggers when a record is updated
  • runs a script, can be as basic as: output.set("hello","world");
  • sends the output of the script to a Slack channel as message.

However, whenever I try to add the output of the script to the Slack message body, I get a popup saying “An error occurred”.
