>                 URL: https://issues.apache.org/jira/browse/CB-13694
>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: cordova-cli
>    Affects Versions: cordova@8.0.0
>         Environment: Mac OS High Sierra, Node v8.9.1
>            Reporter: Vito Macchia
>            Priority: Major
>
> Since updating to cordova-cli 8.0.0 (yesterday) I get 
> UnhandledPromiseRejectionWarnings instead or error prompts with error stacks, 
> which also make difficult to identify bugs/broken deps/missconfigurations.
> Example
> With cordova@7.1.0
> {code}
> cordova prepare
> Error: doc.find is not a function
> {code}
> With cordova@8.0.0
> {code}
> cordova prepare
> (node:2519) UnhandledPromiseRejectionWarning: Unhandled promise rejection 
> (rejection id: 1): TypeError: doc.find is not a function
> (node:2519) [DEP0018] DeprecationWarning: Unhandled promise rejections are 
> deprecated. In the future, promise rejections that are not handled will 
> terminate the Node.js process with a non-zero exit code.
