How can I figure out the porblem in inverting Op-amps

A problem from the Circuit Simulink Course provided by MATLAB. Basically I have done all the required steps but I got stuck in this problem where there's no information about the value of the load resistance.

So I assumed it to be 1 ( which is correct according to the mathmatical equations of inverting op-amps ). in addation to that, I have checked the voltage across the output which is exactly the same as the task is showing and requiring. but I have no idea why it won't allow me to continue any further.

here's the obtained wavefrom of voltage(in yellow) which is the same as the singal requirment

Hi Hussein,

It seems that you are working on "Op Amps > Op Amp Practice (Inverting Amplifier) > Task 5" and facing some issues. Assuming the previous tasks were completed correctly, as the figure suggests, "Task 5" simply requires you to add and correctly connect a "Simscape resistor" to the existing circuit. The model is checked based on this addition alone. However, the inclusion of a "Current Sensor" and a "Voltage Sensor" block seems to interfere with the solution checker.

On reproducing the same model in my Onramp, I encountered an error despite obtaining the correct output. The message indicated, "Each physical network must be connected to exactly one Solver Configuration block." This confirms that adhering to the task's specific requirements should suffice for a successful outcome.

Following is the model created by me for your reference:

Hope this helps!
