CORS even using deleteHeaders function

[carlitomurta]

I installed the library and configured it as specified, I experienced CORS errors with the following
message
"Access to XMLHttpRequest at 'https://logs-01.loggly.com/inputs/<my-token>/tag/AngularJS/' from origin 'http: // localhost: 5000' has been blocked by CORS policy: Response to preflight request does not pass access control check: In 'Access-Control-Allow-Origin' header is present on the requested resource. "
but even using the deleteHeaders function to solve this, keeps happening. No log goes to loggly. I'm using AngularJS v1.6.43
