I keep receiving this problem whenever I save and add a new doc field to a doctype or make any other changes to it. I made this doctype using a custom module.
did you find a solution for this ?,
i am facing the same.
i see there is an validation for validate_set_only_once - which might be a new thing in v14
Is there any solution?
no , this happens when you upgrade your version or get the app from old version ,
you basically have to recreate the whole doctype as new if its custom ,
just duplicate it and maybe add a space to the name
Hi,
I have written small code workaround here:
I hope it helps.
Jiri Sir
Same I am also facing this same issue. How to resolve it?

How to resolve it?
Hello guys,
I was also facing the same issue initially.
I resolved it by running the following command in the system console:
frappe.db.set_value("DocType", "Quotation", "owner", "Administrator")
If you are facing the same issue, please try this on your end and let me know if it works.
