Describe the problem/error/question
I have a workflow that sends a HTTP post to dust.tt. It was working on August 8 - with the exact same json post - and then on following days it’s not working. Everything looks correct and equal to when it was working. It’s only erroring when I drag information from a previous node. So all other aspects of the Json is ok.
What is the error message (if any)?
