How do I send HTTP requests to 1Password Connect server running in AWS?

Options

I followed the documentation and deployed the containers for the Connect server and the API in AWS using CloudFormation. I used the template connect.yaml provided in the 1Password github.
https://github.com/1Password/connect/tree/main/examples/aws-ecs-fargate
I am using postman to test sending a GET request to the external url of the load balancer created by the template but I am getting the following error:
{"status":500,"message":"failed to initiate, review service logs for details"}
I've tried removing different headers in postman and only gotten a 400 Bad Request error.

Edit: I'm looking at the CloudWatch logs and it seems there is an issue with the base64 encoded version of the bearer token (which I also generated per the documentation.) I saw someone else have the same issue here:

The error I'm seeing in cloudwatch says: "illegal base64 data at input byte 1460"
"level": 1
