Error after updating to 13.20.1

Dear all,

we are facing errors after updating our ERPnext installation from 13.19 to 13.20:

Traceback (most recent call last):

The error repeats every few minutes. Anything we can do to fix the issue?

What were the steps you followed for upgrade ?

We did a “pip3 install --user --upgrade frappe-bench” to update the bench first and then a “cd ~/frappe-bench; bench update” to update ERPnext. This is a procedure we have followed over the whole last year without any problems…

Try to run

bench build

Unfortunately that has not changed the behavior. We still do get two messages every three or so minutes, one labeled “pull_from_email_account” with details as shown above, and one labeled “Error” containing “email_account.receive” as error.

I’m not certain how this happens but the receive method fetches uids which are of the type bytes which causes this to break since frappe.db.set_value likes only str types.

I’ll raise a fix for this but for the time being, go to the file frappe/email/doctype/email_account/ and replace line 420 from

frappe.db.set_value("Communication", name, "uid", uid, update_modified=False)


frappe.db.set_value("Communication", name, "uid", frappe.safe_decode(uid), update_modified=False)

and restart your bench. This should do it.

Edit: Raised a PR to fix this


Thanks, Gavin, for your reply & fix. I have applied it and will report back the results.

You’d better repost your problem under an own topic to make sure it is being found by others…
