frappe.exceptions.ValidationError: Options must be a valid DocType for field Sub Category in row 8

can anyone help me

It seems Option field for some link field is not a valid option.

1. bench --site site-name mariadb
2. select name, `options` from `tabCustom Field` where fieldtype='Link';

This will show all custom fields having type link

3. Update invalid option via update query
update `tabCustom Field` set `option` = valid_doc_name where name = field-name

thx for your reply . But i did not find any field name like “sub Category”

Can you share the output for

select name, `options` from `tabCustom Field` where fieldtype='Link';

thx its workout. It shows the duplicate error like this

frappe.exceptions.UniqueValidationError: (u’Desktop Icon’, ‘70e7ad6098’, IntegrityError(1062, “Duplicate entry ‘QA-Administrator-1’ for key ‘unique_module_name_owner_standard’”))

anyone can help me to solve the issue?
