I run odoo16 on docker, and I am coding a search view like this:

​
<record id="purchase_plan_line_search" model="ir.ui.view">
<field name="name">purchase_plan_line.searchfield>
<field name="model">purchase.plan.linefield>
<field name="arch"type="xml">
<field name="task_id"/>
<field name="created_by"/>
<search string="Search Purchase Plan Line">
<separator/>
<group expand="1"string="Group By">
<filter name="group_by_task_id"string="Task"context="{'group_by':'task_id', 'group_expand':True}"/>
<filter name="group_by_request_type"string="Plan Type"context="{'group_by':'request_type'}"/>
<filter name="group_by_verify_option"string="Verify Option"context="{'group_by':'verify_option'}"/>
group>
<filter name="request_type"string="device"domain="[('request_type','=','device_budget')]"/>
<filter name="request_type"string="item"domain="[('request_type','=','item_budget')]"/>
<filter name="request_type"string="maintain"domain="[('request_type','=','maintain_budget')]"/>
search>
field>
record>
<record id='purchase_plan_line_view' model='ir.actions.act_window'>
<field name='name'>Purchas Plan Linesfield>
<field name='type'>ir.actions.act_windowfield>
<field name='res_model'>purchase.plan.linefield>
<field name='view_mode'>tree,formfield>
<field name='search_view_id'ref='purchase_plan_line_search'/>
record>

But when I try to update the application, I raises a ValueError like this:

ValueError: Wrong value for ir.ui.view.type: 'data'

And the following code looks like this:

<record id="purchase_plan_line_search"model="ir.ui.view">
<field name="name">purchase_plan_line.searchfield>
<field name="model">purchase.plan.linefield>
<field name="arch"type="xml">
<data><field name="task_id"/>
<field name="created_by"/>
<search string="Search Purchase Plan Line">
<separator/>
<group expand="1"string="Group By">
<filter name="group_by_task_id"string="Task"context="{'group_by':'task_id', 'group_expand':True}"/>
<filter name="group_by_request_type"string="Plan Type"context="{'group_by':'request_type'}"/>
<filter name="group_by_verify_option"string="Verify Option"context="{'group_by':'verify_option'}"/>
group>
<filter name="request_type"string="device"domain="[('request_type','=','device_budget')]"/>
<filter name="request_type"string="item"domain="[('request_type','=','item_budget')]"/>
<filter name="request_type"string="maintain"domain="[('request_type','=','maintain_budget')]"/>
search>
data>field>
record>

 It adds a in the search view record.

It confuses me a lot, and I have no idea to solve it.

Does anyone know the reason for this?And how to fix it?

Thank you and Regards.
