DateTime doesn't work Moment Timezone problem

[Basdl76]

I have UTC as 'timezone' => 'UTC', in my app.php and DateTime::make('Active from', 'active_from')->nullable(),
But when loading www.domain.com//nova/resources/pages/1/edit?viaResource=&viaResourceId=&viaRelationship= ia m getting this error:

Moment Timezone has no data for UTC. See http://momentjs.com/timezone/docs/#/data-loading/.

@Basdl76 This is an issue we are tracking with the underlying package: I'm baffled by this. If you have any suggestions, we're all ears!

VanOns/laraberg#45

[mikebronner]

@Basdl76 make sure you are running release 0.1.8 of this package. It is using an older version of Laraberg, which does not conflict with the datetimepicker.

Problem 1
- Installation request for genealabs/nova-gutenberg 0.1.8 -> satisfiable by genealabs/nova-gutenberg[0.1.8].
- genealabs/nova-gutenberg 0.1.8 requires van-ons/laraberg v0.0.6-beta -> satisfiable by van-ons/laraberg[v0.0.6-beta]
but these conflict with your requirements or minimum-stability.

Getting a problem. I have "van-ons/laraberg": "^1.0@RC",

@Basdl76 could you post your composer.json for me?

@Basdl76 You have to remove the "van-ons/laraberg": "^1.0@RC", entry from your composer.json.

That did the trick also saving reusable content works. I thought laraberg had also tobe installed. Sorry!

[mikebronner]

@Basdl76 No worries, glad it is now working for you. I will release an update with the latest version of Laraberg integrated once we can get it working properly and not conflicting with Nova fields. :)
