Wierd JavaScript differences between instances (Dashboard with LeafLet Map)

[hbrandt84]

Hi,

I'm currently stumped with with wierd JavaScript problems while migrating a Dashboard with a Leaflet Map from a physical 7.0.1 machine instance to a virtual 7.1.1 one (running on Axure).

I've reduced the Problem to this code:

the script is run successfully on the 7.0.1 instance, but the 7.1.1 has problems.
Namely this part:

with following message:
"leaflet.js:6 Uncaught TypeError: Cannot read property '_leaflet' of null"

But as I see it, its the most barebone way to initialize a new map object.
Plus, the line "console.log(L);" indicates in the js console that L is included and i can browse all functions, even "map:ƒ (e,t)"...

so, I am absolutely clueless what could cause such a different behaviour.
Perhaps a permission issue or something?

Any insight is would be highly appriciated...

thanks,
Henning

p.s.
sorry 'bout the images.
But the tags didn't seem to work for me...

Check out this problem I had some time ago here, maybe it helps if you require leaflet separately (it also had to do with changing versions back then).
