Hello, 

I registered Realm yesterday, and tried to upload(replace) my world to Realm, but i can't.
-> please see attached picture.

Steps

1. Open realm dashbord.
2.  Select a slot.
3. push "Replace world"
4.  choose world
5. The popup said "Export in progress"
6. "World Export finished succesfully."
7. Then, started upload. However, upload progressbar stopped and  "An error occurred".

Versions
