ws-lambda-at-edge-generate-card-page causing 500

[karolhad]

Hi,

I was trying followup this tutorial, but I'm failing at https://github.com/aws-samples/aws-lambda-edge-workshops/tree/master/Workshop1/Lab2_ContentGeneration#12-validate-the-function-works-in-lambda-console

The test returns 500 error with following message:

When I'm opening https://d32at75m0fmpm0.cloudfront.net/templates/card.html in my browser, it returns the template, so I'm not sure what it is wrong.
