Summary

Sometimes when RUM is not available, the console is flooded with console errors that fail the tests

http://localhost:8000/en-US/app/Splunk_TA_UCCExample/configuration - Access to fetch at 'https://rum-ingest.us1.signalfx.com/v1/rumreplay?auth=***' from origin 'http://localhost:8000/' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
