P.S.: Did you know, the concepts of about 70% of questions asked on this forum are already covered in the Make Academy. Investing some effort into it will save you lots of time and frustration using Make later!
Hey man, thanks for the reply. Unfortunately, that didn’t help. I tried to rebuild that upper arm where the error occurs and now suddenly it show the same error but when I connect the Brevo module (“Update a contact” - 29). If I disconnect the scenario before that module, it works. It seems very random and like a bug caused by make.
Found the error. A Gmail module (that came much later) had a GDrive Account filled in as connection instead of a Gmail Account. But for some reason, that specific module never had an error alert.
