Why can't I summon a small_fireball?

I am trying to summon a fire charge with a command block with this:

/summon small_fireball ~ ~1 ~

But, I am getting Invalid command syntax

I have also tried smallfireball and simply doing it in the chat window, but both give me the same message.

What is wrong? I am on Windows 10 edition, if it helps.


This is actually an unresolved bug, and you can't accomplish the task at hand. For some reason, the /summon command won't let you use small_fireball.
