If an http request can't perform the requested operation, should server send 500 error code? Or 200 with status and status message in response?

Isn't 500 used only for unhandled exceptions on server side?

I'm helping my teammates with the problems that they face in debugging an issue or fixing a Dev environment.

Sometimes ppl go too flexible and ask for my Dev VM. The help I have to offer is tell them cause of an issue and tell them the fix that they have to give. What the fu*k they do? What did they gain as experience all these years.

Ppl don't know how to make draft commits. They can't fix but failures. They don't know anything.
They just sit at office and age as it is their only job.
Seniors take so much salary. Why don't they feel bad that they are not doing justice to their work.

Have worked on Java, Objective C, ABAP etc.
Learning JavaScript Basics now. This shit is crazy.
