Hi,

running debian 11 on VPS, imported V14 database to new system, all working but I have a Lead that has the problem identified in this link:

notes for leads created in V13 generate exception after upgrade to V14 · Issue #31800 · frappe/erpnext · GitHub

Problem is I cannot find a way to remove the Lead from current system, I cannot delete the entry it returns error:
