Errors

When coding your node.Node implementation, if you return an error from any function, your http clients will receive a 500 error, but if you want to return an error with a different HTTP status code, you can use or wrap one of the predefined errors

import (
  "github.com/freeconf/yang/fc"
)

  ...
  // Option #1 - straight 401 error
  return fc.UnauthorizedError 

  // Option #2 - enhanced but still an 401 error
  return fmt.Errorf("Bad ACL %w", fc.UnauthorizedError)
