login: improve error message
It looks like the server returns HTML when the authentication fails :/
package gondole
import (
"github.com/sendgrid/rest"
)
// GetCurrentInstance returns current instance information
func (g *Client) GetCurrentInstance() (*Instance, error) {
var i Instance
if err := g.apiCall("instance", rest.Get, nil, &i); err != nil {
return nil, err
}
return &i, nil
}
