                        <action_type>collection</action_type>
                    </route_entity>
                    <route_collection>
                        <route>/testapi</route>
                        <action_type>collection</action_type>
                    </route_collection>
                </routes>
                <versions>1</versions>
            </extendrestapiproductattribute>
        </resources>
    </api2>
</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 ?
