When i install web_gantt it dosen't make an error but instead it shows a js error :

The following modules are needed by other modules but have not been defined, they may not be present in the correct asset bundle:

• @web/core/virtual_hook
• @web/webclient/actions/action_hook 

The following modules could not be loaded because they have unmet dependencies, this is a secondary error which is likely caused by one of the above problems:

• @web_gantt/gantt_renderer
• @web_gantt/gantt_view

Found a solution to : scrollSymbol @web/webclient/actions/action_hook (17), it is at @web/search/action_hook (18) as it changed its place in the directory 

But the @web/core/virtual_hook is now @web/core/virtual_grid_hook
And it's logic is different since it accepts different parameters. 

Still these problems are bypassed until i call the "gantt" view from "hr_work_entry_contract_entreprise" views, it says :

File "/home/alchemycode/Desktop/Alchemy/odoo/odoo18/odoo/fields.py", line 2936, in convert_to_cache

    raise ValueError("Wrong value for %s: %r" % (self, value))

ValueError: Wrong value for ir.actions.act_window.view.view_mode: 'gantt'

odoo.tools.convert.ParseError: while parsing /home/alchemycode/Desktop/Alchemy/odoo/addons_hr_payroll/hr_work_entry_contract_enterprise/views/hr_work_entry_views.xml:4, somewhere inside

<record id="hr_work_entry_action_view_gantt" model="ir.actions.act_window.view">

        <field name="sequence" eval="2"/>

        <field name="view_mode">gantt</field>

        <field name="act_window_id" ref="hr_work_entry.hr_work_entry_action"/>

    </record>

Anyone knows a solution ?
