Where did that error happen down the call chain?

Right at the bottom!

All you need to do is, instead of:

return nil, err

Do:

return nil, wrapperr.WithStack(err)

Also, it is possible to annotate the stack in the middle:

And to get the original error, just used the standard errors.Unwrap(error) function from built-in errors package.
