UI Bug in HTTP (beta) Integrations

Question

I'm creating a new HTTP API using CloudFormation. The template creates a test route with lambda integration. When I view the integration in the UI, it looks bugged, it's missing information and the details are empty. Is my template wrong or is this a bug in the UI?

Hi khatiba,  
  
Thanks for bringing this to our attention. HTTP APIs support 2 ARN formats in the IntegrationUri which I will refer to as "Short Format" and "Long Format". In your template, you're using the Short Format which is just the Lambda ARN. This should work but we have a bug with how we render this on the Console. We'll get this fixed.  
  
In the meantime, you can use the Long Format which will render properly. The long format looks like this:   
arn:aws:apigateway:{api-region}:lambda:path/2015-03-31/functions/arn:aws:lambda:{lambda-region:account-id}:function:{lambda-function-name}/invocations  
  
Let me know if this works.  
  
Thanks,  
Alan

Hi Alan,  
Thanks for the quick reply. I had run across the "long format" you noted, but wasn't sure which to use. I tried it out and the issue is fixed.  
  
Thanks,
