Getting HTTP Error 406 - Not Acceptable. How Do I Fix This? or What Causes HTTP Error 406 and How Can

Had this exact issue yesterday! http error 406 kept popping up until I realized the API was case-sensitive in headers.

Try `Accept: application/JSON` vs `Accept: application/json`—silly, but some servers care.

Also, if you’re using a library like Axios, default headers might be overriding yours. Double-check!
