CROSS error via localhost

Question

I am consuming an angled API and gives me the following error to :

Access to Xmlhttprequest at 'http://localhost:8080/batches' from origin 'http://localhost:4200' has been blocked by CORS policy: No 'Access-Control-Origun' header is present on the requested Resource.

GET http://localhost:8080/lores net:ERR_FAILED

Could someone help me?
