Power Automate PDF send email failing

Jul 15, 03:30 PM (9 minutes ago) Email delivery failed with the message: Value cannot be null. Parameter name: address

I keep getting this error when I try to run a flow or test the process. This was working just a few days ago. I don't understand the error. What value is null? What address? The email addresses look ok to me.

Hello @jdsharp21,

Thank you for the bug report, we have fixed the issue.
Could you please try to save the settings again and restart the process, I suppose it should work as expected now.
