Can you share/show your traceback/screens, and also the versions of your system and OS?

Ubuntu 18.10 (GNU/Linux 4.18.0-15-generic x86_64)

I did bench update / migrate and update batches with no errors, also site migrate, and bench restart

the installation is in production mode

I think some custom field with label Kg is missing.

Your screen shows develop mode, but your post says production mode. It also seems you have a mismatch on the framework vs ERPNext versions. You might need to do a bench migrate so they can sync up

no, Unit of measurement is an original field and is not a custom field. the KG is the value placed on that field and linked to Units of Measurement table Stock_UOM

I did Bench migrate several times, but it keep getting the same.

We pulled updates for V11 from 10, and it upgrades to V12 for ERPNext app

Anyway to fix this

this particular error can only occur if the database is getting an insert command for a non-existant column. Go to Custom Field, filter by Doctype Item and see if there is such a field or not.

bench switch-to-master and then bench update --patch should help erpnext migrate to v11

Did that before, did not fix it

Some patch got missed in update. These column error generally comes when we skip the migrate or update without patches.

so how to fix it??

Something in the lines of what @root13F has suggested about, trying to reapply the patch. Alternatively, Just try to find out Column errors in the forums you should be able to find some fixes.

It seems mysql user password for this site is denied access. It seems further debugging may help.

Dear All, problem solved, but with non of the solutions above.

It was our mistake to upgrade ERPNext app to V12 while frappe and bench is on V11, this caused several problems related to bench update and bench-manager and the ERPNext application fields and some DocTypes.

How we solve it:
First don’t forget to take backup from your sites database - very important (We did that manually from MariaDB), if you forgot you can find previous backups under sites/site name/private/backup

We had removed Bench-manager app manually (removed the folder and site, then remove the database and user)

Re-install Bench manager, and bench manager site

Remove ERPNext app folder manually
Re-install ERPNext App

From banch manager after login after sites ( go to your site and click install APP)

This will install frappe app on the site, then click install app again, it will give you the option to install ERPNext app, select ERPNext and click install

Now your site had been reset, no data, if you try to login you will get the setup wizard

Go to database and restore backup

Then Login again, you will find everything back again.

go to SSH, do Bench update
and Bench update --patch
it should not give you any errors

After login to erpnext app, go to help about
you will find all apps version switched to V11
