List of all error codes?

Hey gang,
I've been getting error 1, 100, and 127, but I can't seem to find an official list of what all of the error codes mean (and what would be causing them/how to solve).

Does this document exist somewhere that I'm just not seeing?

All the best,
Dax.

Very rare you would just get a number from the core. I think that you need to give some more context.
