CORS issues with Basic Auth and angularjs http calls

Hello,

I am trying to create an angularjs app that will call my teamcity( 9.1.7 (build 37573) ) service via API calls.

If i use POSTMAN or PHP everything works, but javascript is having CORS issues

I have already added to the internal.properties file ( and restarted )
rest.cors.optionsRequest.allowUnauthorized=true
rest.cors.origins=http://localhost:8888

I have enabled the debug_auth and i see

[2017-03-10 13:31:43,421]DEBUG [:0:0:0:1; http-nio-5000-exec-9] - Processing request with no authorization header: OPTIONS '/httpAuth/app/rest/projects', from client 0:0:0:0:0:0:0:1:50295, no associated user

From what i have read ( and i am no CORS expert by any means) , the OPTIONS call is suppose to exclude users credentials

Thanks for any help
