Clicking on odoo menu show `Document empty` error - view

Question

I am getting the following error on odoo 15.0 when clicking on menu Time Off/Approvals/Time Off
This menu is linked to the action
open_view_holiday_status
from odoo module's hr_holidays which in turn is linked to the view tree
view_holiday_status_normal_tree
I have extended that view the following way in a module named hr_holidays_base:
<record id="holiday_status_base_tree" model="ir.ui.view">
<field name="name">hr.holidays.status.tree</field>
<field name="model">hr.leave.type</field>
<field name="inherit_id" ref="hr_holidays.view_holiday_status_normal_tree" />
<field name="priority" eval="1" />
<field name="arch" type="xml">
<field name='display_name' position="after">
<field
name="max_leaves"
invisible="not context.get('active_id',False)"
/>
<field
name="leaves_taken"
invisible="not context.get('active_id',False)"
/>
<field
name="remaining_leaves"
invisible=" not context.get('active_id',False)"
/>
</field>
</field>
</record>
Note: i have a second view tree extending from it too:
<record id="secondary_holiday_status_base_tree" model="ir.ui.view">
<field name="name">secondary.hr.holidays.status.tree</field>
<field name="model">hr.leave.type</field>
<field name="inherit_id" ref="hr_holidays_base.holiday_status_base_tree" />
<field name="mode">primary</field>
<field name="priority" eval="15" />
<field name="arch" type="xml">
<field name="company_id" position="attributes">
<attribute name="invisible">1</attribute>
</field>
</field>
</record>
Now getting the error:
Error:
Traceback (most recent call last):
File "/usr/local/lib/python3.10/dist-packages/odoo/http.py", line 643, in _handle_exception
return super(JsonRequest, self)._handle_exception(exception)

raise exception.with_traceback(None) from new_cause
File "<string>", line 1
lxml.etree.XMLSyntaxError: Document is empty, line 1, column 1
What could go wrong? any hint maybe?
I have tried following the execution of every step by step. I have searched these defined views from the UI and they work well individually. The only issue is when trying on that menu and this is where it shows the error
