Spacetime isn't a medium - there is no aether.

If I understand your poorly worded question, you are asking if space and time are required for an electromagnetic wave to travel through the universe.
The answer is both YES and moot. Yes, because an electromagnetic wave, or any other mass or energy, must have both a space to exist in and and a length of time in which to exist.
But since both space and time DO exist, your question is in fact, moot, without any point or purpose.

The question is not clear. But the medium of travel for electromagnetic waves is named as ether.

No space-time was just a mathematical tool to explain relativity effects. It's not a real thing; just a bunch of formulas and graphs. EM waves only need space to propagate. Maxwell's equations predicted EM waves without any reference to space-time. EM waves don't need a medium. That's what killed the ether theory.
