Erpnext: [v12] Can't send Documents via Email after upgrading to v12

[ophl55]

Installed Apps
ERPNext: v12.1.2 (version-12)
Frappe Framework: v12.0.12 (version-12)

After upgrading to ERPNext v12 I receive the following error when I try to send a document via email.

[ophl55]

When I click on "Bericht" (report) the message tells me that a support email is not given. Does that rely to the error or is it just an info that no default support email is available?

[Mitchy25]

You need to create an Email Address and set it as Default Outgoing or setup the email account in the user record.

[ophl55]

Thanks for your reply. Everything has been set already in v11 before the upgrade. Do I have to reset the email setup?

The notification email is set as my default outgoing email address and that worked in v11.

[ophl55]

I've just deleted the old email-address and created a new one. The error persists.

• Can you check if python files for Communication DocType exists
• I had encountered somewhat the same issue and turned out that Communication DocType fiels were deleted.

There are python files in

• erpnext/erpnext/communication/call_log
• erpnext/erpnext/communication/communication_medium
• erpnext/erpnext/communication/communication_medium_timeslot

How did you fix the issue?

[ophl55]

It is still not possible for me to send emails. Has anyone an idea how to fix it?

I was able to narrow down the error.

The first issue is related to timeline links.

In https://github.com/frappe/frappe/blob/develop/frappe/core/doctype/communication/communication.py I commented out line 65 and 66

if self.communication_medium == "Email":
  self.parse_email_for_timeline_links()
  # self.set_timeline_links()
  # self.deduplicate_timeline_links()

Timeline links is a new feature introduced in v12 (see https://erpnext.com/docs/user/manual/en/setting-up/email/linking-emails-to-document).

I have disabled the automatic linking in my email account. I suppose that the two methods should not be executed in that case.

Can anyone of the frappe core team please check that? @clarkejj

Another problem arises with smtp because of python3.6:

(501, b'Syntax error - line too long')
Traceback (most recent call last):
  File "/home/frappe/frappe-bench/apps/frappe/frappe/email/queue.py", line 406, in send_one

  File "/usr/lib64/python3.6/smtplib.py", line 888, in sendmail
    raise SMTPDataError(code, resp)
smtplib.SMTPDataError: (501, b'Syntax error - line too long')

After migrating back to python2.7 emails are sent with attachements as expected.

• The problem is Communication doctype wasn't reloaded properly, so the code is new but the doctype structure is old which is causing this error.
• Goto python console and reload the communication and communication_link doctype and this should be fixed.

[jigneshpshah]

Thanks @hrwX

this solved.

bench --force reload-doc core doctype communication_link
bench --force reload-doc core doctype communication

[ophl55]

Can confirm that reloading the doctypes worked. Thx for the support!

@ophl55 @jigneshpshah - Does the smtp issue with python3.6 also resolve with above command?
