Getting the following with 1.1.0. Solved this by reverting back to 1.0.1

C:\sites\rtview-cloud-api\node_modules\loopback-ds-readonly-mixin\lib\read-only.js:65
    Object.keys(Model.definition.settings.relations).forEach(relationName => {

I think that the issue is that some of my model json files don't have relation properties. Perhaps you shoul do do check to see if relations exists?
