Hi,
I’m trying to get my first very simple workflow to work. I want to monitor an email inbox with the IMAP trigger task, filter the incoming emails by their subject, and in some cases send the contents of the email to another email address via SMTP. Any info on how to fix this issue would be much appreciated!
Best Regards, Fredrik
What is the error message (if any)?
In the very last step (sending via SMTP) an error window pops up with this text:
There was a problem executing the workflow:
"Converting circular structure to JSON → starting at object with constructor ‘Object’ — property ‘issuerCertificate’ closes the circle"
Please share the workflow

As I’m not transforming the data, it is just je normal output of the imap trigger.
