Hi
What is the error message (if any)?
When I run my workflow that uses the send and wait for approval email node to get approval on an email, I can respond to it once and then I have an AI model afterwards, which should see the free text response and then rewrite the email and give it back to me based on that and then send it for approval again. However, when the loop restarts it always get’s stuck at the send and wait for approval node. If I reopen the first email and respond again then the node executes. How can I be sent a new email for each time I enter in something in the free text other than yes (confirming it’s good to go)?
Thanks for the help
I only put in the wait node for experimenting:
