Odoo16迁移至Odoo17时search_read无指定字段报错问题

在将数据从Odoo 16迁移到Odoo 17的过程中，出现以下异常情况：

• 调用search_read方法不指定具体字段时，执行代码：

res = models.execute_kw(db, uid, password, the_class, 'search_read', [domain], {'limit': 1})

会触发错误：'_unknown' object has no attribute 'id'

• 但明确指定字段（例如仅获取name字段）时，操作可正常完成，执行代码：

res = models.execute_kw(db, uid, password, the_class, 'search_read', [domain], {'fields': ['name'], 'limit': 1})
