500 error on /genClassCertificate

[laura-arditti]

I have completed the course "Using a Machine Learning Workflow for Link Prediction" and correctly answered all quizzes at the end of each section. However, when I click on the "Download certificate" button, it displays the message

Certificate not available yet.
Did you complete the quizzes at the end of each section?

By inspecting the console, I see that after clicking the button a request is made which results in the error below

bizible.js:126 POST https://pysadbr27c.execute-api.us-east-1.amazonaws.com/genClassCertificate 500
XMLHttpRequest.send @ bizible.js:126
jr @ site.js:1
Or @ site.js:1
getClassCertificate @ site.js:1
document.addEventListener.document.querySelectorAll.forEach.t.onclick @ site.js:1
site.js:1 Unable to get the certificate {"message":"Internal Server Error"}

This makes it impossible to download the certificate. I believe this is an issue with the neo4j graphacademy api itself so I'm opening this issue hoping it may help.
