I have a zap created a long time ago that has always worked. I put some excel files in a Drive folder and I send them by SMTP. The name of this file is the same as the address of the recipient (email@example.com). With SMTP by ZAPIER (but also with Gmail) I send an email to the recipient's address (firstname.lastname@example.org) with the file with the same name attached (email@example.com)
. The zap has always worked. Today it doesn't work and it gives me this error:
“The app returned "Error 400 (Bad Request)!!1".
After I did some tests I realized that the problem is the attachment. Without attachment it gives no error. What do you think I need to change or check?
