<extendrestapi translate="title" module="api2">
<title>Extended Rest API</title>
<sort_order>10</sort_order>
</extendrestapi>
</resource_groups>
<resources>
<extendrestapicategory translate="title" module="api2">

<action_type>collection</action_type>
</route_collection>
</routes>
<versions>1</versions>
</extendrestapiproductattribute>
</resources>

</config>
I do not know why I run this url http://localhost/magento_4/api/rest/ikom/testapi/1, this have response {"messages":{"error":[{"code":404,"message":"Request does not match any route."}]}}.
What wrong here ?
