Getting error "xa-resource-0 is not found at specified s3 location" while configuring application in Microfocus runtime environment.

I am following a AWS documentation tutorial (https://docs.aws.amazon.com/m2/latest/userguide/tutorial-runtime-mf.html) where I am creating an application for Microfocus runtime environment in AWS Mainframe Modernization sevice. I have performed all the previous steps mentioned in doc. At Create an application step, I am getting error "Application demo-app failed to create. resource object with id xa-resource-0 is not found at specified s3 location" while specifying resource and configuration.

This is the script for specifying resource and configuration.
