When a view is created, look for common mistakes and print something to the console log that there may be a problem. Still keeping running – just print an info message.
When the (incorrect) client gets used, the failure message logged doesn't offer any guidance as to what might be wrong.
Things to look for:
spaces in path that aren'ts. For example, there are three spaces in one view mapping line but not any quotes.
left side ends with "..." but right side doesn't. And vice versa.
