menuItemClass is not defined

[xauxatz]

When I try to generate my project with Blaze/Materialize, I get the above error when running the project: menuItemClass is not defined

With more detail: Exception in template helper: ReferenceError: menuItemClass is not defined at Object.Helpers.menuItemClass (http://localhost:3000/app/app.js?hash=bfe7a65c4dddd3268a8bf3387edbff92e9ac98ea:3200:3) at http://localhost:3000/packages/blaze.js?hash=51f4a3bdae106610ee48d8eff291f3628713d847:3051:16 at http://localhost:3000/packages/blaze.js?hash=51f4a3bdae106610ee48d8eff291f3628713d847:1715:16 at http://localhost:3000/packages/blaze.js?hash=51f4a3bdae106610ee48d8eff291f3628713d847:3103:66 at Function.Template._withTemplateInstanceFunc (http://localhost:3000/packages/blaze.js?hash=51f4a3bdae106610ee48d8eff291f3628713d847:3769:14) at http://localhost:3000/packages/blaze.js?hash=51f4a3bdae106610ee48d8eff291f3628713d847:3102:27 at Spacebars.call (http://localhost:3000/packages/spacebars.js?hash=6f2be25813c793c0b363a6a91ebb029723f294ec:172:18) at Spacebars.mustacheImpl (http://localhost:3000/packages/spacebars.js?hash=6f2be25813c793c0b363a6a91ebb029723f294ec:106:25) at Object.Spacebars.mustache (http://localhost:3000/packages/spacebars.js?hash=6f2be25813c793c0b363a6a91ebb029723f294ec:110:39) at class (http://localhost:3000/app/app.js?hash=bfe7a65c4dddd3268a8bf3387edbff92e9ac98ea:1675:24)
