Error - Direction line must lie in plane of boundary or sour

Hi,
I'm new to HFSS. I got this Dipole example from this forum. On running a Validation check, I'm getting this error, "Direction line must lie in the plane of the boundary or source."

I'm also attaching the HFSS file. Can anyone tell me what the issue is.
Thanks,

Hi hkprakash7!

Interesting enough, I didn't get any error message. My HFSS version is 11.1
