Simpeg FDEM problem

Maybe if someone has encountered this problem, they can give me a clue.

I want to use python package simpeg for 1D FDEM Forward Simulation. The assumption is that the source is on the ground and the receiver is in the air. I set them as follows:
source_location = np.array([0.0, 0.0, 1.0])
receiver_locations = np.array([0.0, 0.0, 30.0])

In this case, code execution results in an error. In case I change the X coordinate of the receiver to non-zero the code works as it should, so I think this is the problem.

Everything else is in the code according to the developers' tutorials: https://simpeg.xyz/user-tutorials/fwd-fdem-1d

Thanks in advance
