Get Invoices API not working Fusion Financial Cloud

Summary

500 Internal Server Error

Content

I have managed to successfully test many Rest API's in Postman however the Invoices API returns a '500 Internal Server Error'.

I believe it is to do with authorisation as Postman also provides this message 'This request is not inheriting any authorization helper at the moment'

The account used does have access to review invoices.

Any ideas, thanks
