Can't locate issue

I have been trying all day to figure out where this Fluxor error is coming from. Any help would be greatly appreciated.

Try setting this attribute on StoreInitializer to catch unhandled exceptions.

I'll close this. Please let me know if I need to reopen it.

I am getting the same error. Could you solve it? Thank you!

[mrpmorris]

Can you paste the stack trace in the exception please?

Hi, yes, here's mine:

It seems that the issue was on our end. We were trying to access a variable when it wasn't loaded yet. Thank you
