Hi All, I am having trouble posting my blocks to slack. I am not sure whether to put the JSON in the text post field, or if I need to format the post within slack. I currently have a JSON blob that I’ve validated in the Slack block builder but I keep getting errors when I try to post with blocks, and if I use the text field it just posts the JSON to the slack channel without formatting it. Any ideas? I am adding the workflow here:
