I’m seeing on my existing scenario a bunch of errors on the Gmail module that I’m not familiar with. I haven’t seen those before but am getting them now on almost every run. Has anyone encountered those?

Highly recommend against using Gmail as a bulk email sender. Try mailgun and sendgrid as alternatives. They are made for bulk email sending. You’re breaking the TOS for Gmail.
