Cannot read property 'name' of undefined

While playing with ocLazyLoad, I got the following error:

TypeError: Cannot read property 'name' of undefined
    at ocLazyLoad.js:554
    at Object.forEach (angular.js:336)
    at Object._loadDependencies (ocLazyLoad.js:539)
    at loadNext (ocLazyLoad.js:642)

Can you spot the error?

// directives
'ngTagsInput',
'ui.pagedown',
'puElasticInput',
'ui.bootstrap'

[
    'sharedState.appWide.files',
    'oitozero.ngSweetAlert.files',

Yeah, I just forgot the comma between 'ui.bootstrap' and the opening square bracket. Should be a syntax error, but due to javascript dynamic nature, it's not flagged as syntax error. Should explore JSLint.
