C1_W1_Lab04_Gradient_Descent_Soln: can't download as pdf

Lab C1_W1-Lab04_Gradient_Descent_Soln:
When I go File > Download as > pdf, I see 500 Internal Server Error

And this is not the only one I see this error when I download as pdf,
I can’t download as pdf in many labs and programming assignments.
This is very annoying. Can you please fix so that I can download it as PDF?

Download as PDF doesn’t work. It never has for several years.
It is unlikely to be fixed.
