Kia ora chandrantwins, I don't know if you are still having issues with this but I just encountered the same problem but have managed to resolve it so I thought at the very least I will post for future users. I was trying to use the reference entity media files endpoint.

For me, the issue was that in Postman Content-Type was being set in two locations - in the Headers and in the Body (as the file is being added under the 'form-data' section).

Postman says that Content-Type header in the Headers section will be overridden but it seems to only fail when this is set as well:

This might actually be more of a Postman issue as it feels like what the pop-up dialogue is saying is not actually being followed.

Hope this helps :)
