Illegal Photo View Id Issue

Options

I've checked everywhere and I understand I have to instantiate using photon.

But here's my scenario:
I have a jump pad game object. This game object is pre-placed in the scene for level design. So if any players steps on this jump pad, the jump pad will call an RPC to inform everyone on who are being propelled from the jump pad.

So how do I go about with this if I can't instantiate on runtime? There are a number of of jump pads and similar interactive objects pre-placed in the scene as part of level design.
