This problem has already been asked multiple times on MATLAB Answers.
I strongly suggest you go through the forum and see what the discussion there.
Also, Onramps provide solutions for problems in the assignment itself. You can refer that as well.

I've already done that, but non of the answers were suitable to this error.
As for the solution provided by the training itself, it only included how to input the required paramaters.
Thank you though!

The error stems from the fact that there is an Electrical Reference which is connected to the Solver configuration.
Delete it and the model will pass the test.

I tried what you said, but still the issue is not solved.

Ah, Idk how I picked the right thing but didn't convey it rightly. Anyways -
The negative connection from Rotational Electromechanical Converter should connect to the input of Controlled Voltage Source (negative), not the output (positive).
See the attached image.
