Variables

View Source 
var ErrBadRequest = errors.Wrap(ErrNotOK, "recv 400 BadRequest response from API")

ErrBadRequest specifically means that a '400 - BAD REQUEST' response was received from the API.

View Source 
var ErrNoContent = errors.New("recv 204 no content response from API, No header is available")

ErrNoContent specifically means that a '204 - No Content' response was received from the API. Typically, a 204 is a success but in this case for the Header API means No header is available

View Source 
var ErrNotFound = errors.Wrap(ErrNotOK, "recv 404 NotFound response from API")

ErrNotFound specifically means that a '404 - NOT FOUND' response was received from the API.

View Source 
var ErrNotOK = errors.New("did not receive 200 response from API")

ErrNotOK is used to indicate when an HTTP request to the Beacon Node API failed with any non-2xx response code. More specific errors may be returned, but an error in reaction to a non-2xx response will always wrap ErrNotOK.
