Any help will be appreciated.

By curiosity, are you modifying the doc from ‘Doctype List’ or ‘Customize Form’?
I recall getting an error when I first try to modify something when I passed by ‘Doctype List’ instead of ‘Customize Form’ for Core document.

I think their is no

just review your code maybe you miss it

Hello @mel_erp and @kkulloters,
I have tried to customize “Doctype list” . After adding custom field in “Doctype list” i had above error , but i have solved it . Using bench command “Bench migrate” in source code.
Why this thing happend after customized Doctype Document?

because the db is not updated

as @kkulloters says it’s not updated. This is why we use Customize From instead. You’ll be able to see the changes when you click on ‘Update’. Also, you’ll be able to export the changes from one environment to another, so you won’t have to do this manually each time you want to export your changes.
Basically, it’s not a good idea to pass by ‘Doctype List’. Customize Form is your friend :wink:
