Are the # characters in the beginning of every line? If so you have to remove them as that's making it a comment.

Well spotted but that was a typo and I have now updated the main post. I copied that from the apps.yaml as it is now, I commented it out so I can easily retest later. I have to comment out as having it fail makes predbat fail to complete to load as it hangs on the kraken part.
