I have the exact same problem :( searching works fine but I have the same error in my console.
Edit: Are you also using InteractiveServerRenderMode ?

[EGInsider]

@Greenspart yeah searching works fine but error pops up on console....not sure of InteractiveServerRenderMode setting. Can you give me a reference or sample code?

I can't reproduce it. Could you try with the latest (v 7.1.0)?
