When I run zcli apps:validate it tells me that JSHint validation failed. When I run JSHint on it's own it doesn't show me any errors
When I try to upload my app zip file it gives me an error but I cant seem to be able to track down what the error is "Unexpected token T" or get the rest of the error message.
I've created a ticket for this in order to take a closer look at your app.
