Solved.

Go to /home/frappe/frappe-bench/apps/frappe/frappe/email Folder

Replace the content of email_body.py with content from:

github.com

frappe/frappe/blob/v13.0.0-beta.1/frappe/email/email_body.py

Hi, thank you but now it says
_recipients=expose_recipients)

I’m facing this after minor updating v11 and then upgrading to v12. I also updated the email password since I could not get the previously saved password to work (encryption key not found, maybe this was my mistake) so I updated the password for the email account and can successfully save.

chris_myzel · August 12, 2020, 8:22am

thank you very much - this works for me!

OneiricIT · August 18, 2020, 8:09am

Thanks - this sorted it out for us too. Nothing hitting our email queue at all.
Completed minor update from 12.7.x up to 12.8.4 which started this.

it gives message User None not found

wale · October 28, 2020, 4:19pm

I got around this by upgrading python version to 3.7 and migrating the environment accordingly:

Upgrade to python 3.7
bench migrate-env python3.7

Cheers

neelbhanushali · March 22, 2021, 5:11am

@wale
can you also mention what does migrating to python@3.7 actually do?

neelbhanushali · March 22, 2021, 5:24am

@Narahari_Dasa

can you mention why does it start working after replacing v13’s email body?

@nabinhait
can this release be made for v12?
facing this error on frappe version 12.14.0

wale · March 23, 2021, 7:50am

As I already mentioned on Github, I believe there were some bugs / compatibility issues with 3.6 so 3.7 was more generally recommended

Cheers

Narahari_Dasa · April 10, 2021, 4:57am

It is because of Python Version issue. This problem solution is for v3.6. For v3.7, this is not even a problem.
