SAP UI5 Issue - No 'Access-Control-Allow-Origin' header

Dear Expert,

We are facing Issue in Chome of "Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:50946' is therefore not allowed access. The response had HTTP status code 405."

While testing the Application.

Please guide us on the same.

Thanks
