# Network header missing in Zipy

Please verify that the server at your end, has listed the headers with the `Access-Control-Expose-Headers` header. The response headers should have this header listed along with other headers. 

In case of a cross-origin request, this header allows a server to indicate which response headers should be made available to scripts running in the browser. 

To know more about this header check here - [ https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Expose-Headers ](< https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Expose-Headers >)
