Hola, he instalado tu aplicación. Ningún gráfico quiere generar, no sé qué puedo hacer al respecto. Estoy recibiendo un error: http://localhost/wallet/simulator?id=1

Empareje mi billetera con coinbase-pro. Los valores han sido importados pero no hay valor actual, etc.

Por favor ayuda

ErrorException:
