Dashboard `500 Internal Server Error`

Hi

I moved from a vm based has / appdaemon to HASSIO

Installed appdaemon via the hassio web ui. Started ok and i can see the hello dashboard

copied my dashboard file over, pretty basic really and references the same entities, and i get a server error when loading it

`500 Internal Server Error`
`Server got itself in trouble`

I tried to add just the clock into the hello.dash, and i get the same error on that one too!

Not sure where to start, thought being an automated install it would work.

Here is the log - https://pastebin.com/LfuqZZX0

you have things inside your dashboard that are not right in yaml.
maybe due to copy pasting (wrong characters), or indention errors.
