OMF & CORS

I’ve developed a few Python based examples and it works well, but I have been struggling to get a JavaScript example to work.

(ref - https://github.com/osisoft/OMF-Samples/tree/master/Community%20Samples/JavaScript%20and%20HTML)

It seems to be a CORS / pre-flight header type issue.

Do you have any information / work arounds regarding how to configure the PI Connector Relay / PI Data Collection Manager services to allow CORS?
