@nobuQuartile Can you check with my suggestion code?

@api.model
    def fields_view_get(
        self, view_id=None, view_type="form", toolbar=False, submenu=False
    ):
        res = super(Base, self).fields_view_get(
            view_id=view_id, view_type=view_type, toolbar=toolbar, submenu=submenu
        )
        arch = etree.fromstring(res["arch"])
        model = self.env["ir.model"]._get(self._name)
        if view_type == "tree" and model.add_open_tab_field:
            res.setdefault("fields", {})
            if "id" not in res["fields"]:
                res["fields"].update(self.fields_get(["id"]))
            id_elem = """<field name="id" widget="open_tab" nolabel="1"/>"""
            id_elem = etree.fromstring(id_elem)
            tree = arch.xpath("//tree")[0]
            name_field = self._get_name_field(tree)
            if name_field:
                tree.insert(name_field[0].getparent().index(name_field[0]) + 1, id_elem)
            else:
                tree.insert(0, id_elem)
        res["arch"] = etree.tostring(arch, encoding="utf-8")
        return res

@AungKoKoLin1997 Your code also works well.

@nobuQuartile Please describe the cause of the issue, or it's hard to understand the validity of the solution.

In what situation could res["fields"] be missing?
