Fatal Error: could not create List from JSON

[fabien]

An app crashes when a 'list' (array) property doesn't receive the correct input:

"tags": {
  "type": ["string"]
}

REST Request (pseudo code): POST { "tags": "one" } (should have been array not string)

Error: could not create List from JSON string: at new List (<...>/node_modules/loopback-datasource-juggler/lib/list.js:16:13)

This should be handled gracefully by any means, not bail out completely! (perhaps even cast a scalar to an single-item array). A more extensible approach would be custom formatters/converters/coercing - see #128

I agree. Another way to handle the errors gracefully is to use domain or Zone, which might introduce quite a bit overhead.
