as you have renamed the field in the past, please run bench clear-cache, then check via bench console whether type of the field in question is Link or Data?
Hi @szufisher, thanks for your response. Could you please give a bit more guidance on how to do this ?
Thanks
I’ve just experiencing exactly same issue here…
The different is, I used server script that call frappe.get_doc and insert() just like this
project_cost = frappe.get_doc({
"doctype": "Project Cost",
"project": i,
})
project_cost.insert()
and field project is called in fetch from at another field
then it’s become unvalidated and document still created…
