Hi,

Couldn't see your code if its for report i think this might be the most common issue causing for external Id in common Reports is

Correct format of Report
        <record id="action_report_tour_tour" model="ir.actions.report">
        <field name="name">Tour</field>
        <field name="model">tour.tour</field>
<field name="report_type">qweb-pdf</field>
<field name="report_name">travel_management_system.report_tour_tour</field>
<field name="report_file">travel_management_system.report_tour_tour</field>
<field name="print_report_name">'Tour - %s' % object.name</field>
        <field name="binding_model_id" ref="model_tour_tour"/>
<field name="binding_type">report</field>
    </record>

Write the Report like this

If the Report is like not in the correct format it will cause external Id Issue

for example

    <record id="action_report_tour_tour" model="ir.actions.report">
        <field name="name">Tour</field>
        <field name="model">tour.tour</field>
<field name="report_type">qweb-pdf</field>
        <field name="report_name">
travel_management_system.report_tour_tour
        </field>
        <field name="report_file">
travel_management_system.report_tour_tour
        </field>
<field name="print_report_name">'Tour - %s' % http://object.name" target="_blank" data-saferedirecturl="object.name</field>
 " rel="ugc">https://www.google.com/url?q=http://object.name&source=gmail&ust=1707364062711000&usg=AOvVaw2tAdSSiuFEZpVQ3bQ6tyDR">object.name</field>
        <field name="binding_model_id" ref="model_tour_tour"/>
<field name="binding_type">report</field>
    </record>

Hope it helps
