While sending a request to dynamically create a purchase order based off invoices we receive from our vendors I am getting the following error:

HTTP/2 400 date: Thu, 10 Sep 2020 15:13:29 GMT content-type: text/html; charset=utf-8 content-length: 71 server: Apache/2.4.41 (Amazon) mod\_wsgi/3.5 Python/3.6.10 {“message”: “Unexpected error. Please contact a system administrator.”}

Can someone point me in the right direction on how to diagnose what’s causing this issue?

Hi @mishawn  
Are you still seeing the error upon retry?  
Is there any chance you could share the Mutation here (with dummy data)  
Thanks in advance!
