Error : 'An exception occurred executing JS interop: The JSON value could not be converted to System.Boolean. Path: $ | LineNumber: 0 | BytePositionInLine: 4.. See InnerException for more details.'

my code

    [Inject] IJSRuntime js { get; set; }

    private async Task OnRowRemoved(UsuarioArea usuarioArea)
    {
        bool confirmacion = false; 
        confirmacion = await js.InvokeAsync<bool>("customConfirm","Desasignar area","¿Quiere desasignar estar area?","question");
        if (confirmacion) 
        {
            Console.WriteLine("Si");
        }else{
            Console.WriteLine("No");
        }
  }

JS (Code From Felipe Gavilan, Youtuber)

function customConfirm(title, text, type) {
    return new Promise(resolve => {
        Swal.fire({
            title,
            text,
            type,
            showCancelButton: true,
            confirmButtonColor: '#3085d6',
            cancelButtonColor: '#d33',
            confirmButtonText: 'Si, Eliminar'
        }).then((result) => {
            resolve(result.isConfirmed);
        })
    });
}
