In a Cloudformation template, how can I can I get a Batch::JobDefinition and Batch::JobQueue name, so I can pass them into a Lambda as a variable?

I have tried pulling it out with !GetAtt using JobQueueName name QueueName but it all fails on updating the stack. Using !Ref only gives me the arn, which I can't use in the JS SDK to communicate with the batch processing.

Both resources, AWS::Batch::JobQueue and AWS::Batch::JobDefinition, only have the function Ref enabled to return the arn, you can't get any other value of those resources. What you can do is to use the function Fn::Split and Fn::Select to obtain their names based on the arn. For example,

1. 
   

   For the JobQueue, with arn arn:aws:batch:us-east-1:111122223333:job-queue/HighPriority, this code will return HighPriority.

   
   
   

   !Select [1 , !Split ["/", !Select [5, !Split [":", !Ref JobQueue]]]
   
   

   
   


2. 
   

   For the JobDefinition, with arn arn:aws:batch:us-east-1:111122223333:job-definition/test-gpu:2, this code will return test-gpu.

   
   
   

   !Select [1 , !Split ["/", !Select [5, !Split [":", !Ref JobDefinition]]]
