Updating a SPFx app: Can't find FC-namespace

[Americo Perez]

Hi,

I am trying to update this application: js-modern-calendar and I found that it is using a namespace that I can't find, it is "FC" and the app is calling a method in this namespace called "EventObject()" in the "ModernCalendarWebPart.ts"-file in the row 39. The app isn't written with the last SPFx version and that's why I am trying to update it. 

I started from a scratch proyect created with "yo @Pernille-Eskebo/sharepoint" but I am fast since I can't find the "FC" namespace.

Any idea where is this namespace comming from? or what package I need to install to have access to it?

I have checked the package.json and both looks similar, the differences are the version numbers, mine are newer than the one used in the original app.

Best regards

FC is the namespace used by the fullcalendar plugin. I had the same issue when trying to get the sample to work and was able to resolve it by specifying dependency 'fullcalendar' to 3.2.0 (not ^3.2.0). By default npm install grabs the latest fullcalendar which breaks the app, but 3.2.0 seems to work.
