I am getting the following error using angular js to call an OSB Rest proxy service endpoint
Failed to load resource: the server responded with a status of 500 (Internal Server Error) (14:01:33:584 | error, network)
at http:/servername:8011/Test_SB/ProxyService/ProxyService_TEST_PS
XMLHttpRequest cannot load http://servername:8011/Test_SB/ProxyService/ProxyService_TEST_PS. 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:8383' is therefore not allowed access. The response had HTTP status code 500. (14:01:33:599 | error, javascript)
How can I resolve? I tried adding a transport header activity to the response pipeline that sends back ‘Access-Control-Allow-Origin' with the value * but that did not resolve
