Error

ValueError: Wrong value for ir.ui.menu.action: 'form,765'

raise ValueError("Wrong value for %s: %r" % (self, value)) odoo.tools.convert.ParseError: "Wrong value for ir.ui.menu.action: 'form,765'"

You need to provide a valid action (ir.actions.act_window) to the menu item, not a form view (ir.ui.view).

Check the following example taken from Building a module/Actions and Menus:

    <?xml version="1.0" encoding="UTF-8"?>
<odoo>

        <!-- window action -->
        <!--
            The following tag is an action definition for a "window action",
            that is an action opening a view or a set of views
        -->
        <record model="ir.actions.act_window" id="course_list_action">   <!-- Action definition -->
            <field name="name">Courses</field>
            <field name="res_model">openacademy.course</field>
            <field name="view_mode">tree,form</field>
            <field name="help" type="html">
                <p class="o_view_nocontent_smiling_face">Create the first course
                </p>
            </field>
        </record>

        <!-- top level menu: no parent -->
        <menuitem id="main_openacademy_menu" name="Open Academy"/>
        <!-- A first level in the left side menu is needed
             before using action= attribute -->
        <menuitem id="openacademy_menu" name="Open Academy"
                  parent="main_openacademy_menu"/>
        <!-- the following menuitem should appear *after*
             its parent openacademy_menu and *after* its
             action course_list_action -->
        <menuitem id="courses_menu" name="Courses" parent="openacademy_menu"
                  action="course_list_action"/>                           <!-- specify the ation -->
        <!-- Full id location:
             action="openacademy.course_list_action"
             It is not required when it is the same module -->
