Running into CORS error with REST API

Hello!

When trying to make a request via the REST API from within a Formula - Rich Text field in QB, I'm getting a CORS request error.  I'm able to successfully execute the request within the developer.quickbase.com portal, so I'm guessing it's not an issue with an invalid user token.  I've used the XML API extensively but never had to deal with the cross-origin issue.  Anyone have any guidance on what I might be doing wrong?  Thanks in advance for any help!
