XML templating in fragment error

Hi experts.

I am trying to use xml template in fragment but it does not work and i am getting error below.

Uncaught Error: failed to load 'http://schemas/sap/com/sapui5/extension/sap/ui/core/template/1/repeat.js' from ../../resources/http://schemas/sap/com/sapui5/extension/sap/ui/core/template/1/repeat.js: 404 -

In fragment i use namespace

xmlns:template="http://schemas.sap.com/sapui5/extension/sap.ui.core.template/1"

How to resolve this issue ?
