Thanks for the report, are you able to share an example of the contents of the PATCH payload?

[dimasrespect]

I think, i found the problem. It's here:

gitea/routers/api/v1/repo/issue.go

Line 836 in f05d9c9

if (form.RemoveDeadline == nil || !*form.RemoveDeadline) && !form.Deadline.IsZero() {

Some additional check is required here. I'm making request with "unset_due_date": false and i'm not providing due_date field. In this case form.Deadline is undefined and error happens. So there are should be additional check, something like this:
if (form.RemoveDeadline == nil || !*form.RemoveDeadline) && form.Deadline != nil && !form.Deadline.IsZero() {

[dimasrespect]

Here is sample payload to reproduce issue:
{ "assignee": "user_login", "assignees": [ "user_login" ], "body": "custom comment", "milestone": 0, "title": "Edited issue", "unset_due_date": false }

[dimasrespect]

Or may be it should return 412 error (bad request) in this case? So can understand that i'm doing something wrong ;)

[Zettat123]

I think a 400 error should be returned if the unset_due_date is set to false without providing a due_date
