panic when creating a new spreadsheet

[adejoux]

Hello,

Thanks for your work.

I tested it with the code below but I have a crash when creating a new spreadsheet:

package main

import (
    "context"
    "io/ioutil"

    "github.com/Iwark/spreadsheet"
    "golang.org/x/oauth2/google"
)

func main() {
    data, err := ioutil.ReadFile("client_secret.json")
    checkError(err)
    conf, err := google.JWTConfigFromJSON(data, spreadsheet.Scope)
    checkError(err)
    client := conf.Client(context.TODO())
    service := spreadsheet.NewServiceWithClient(client)

    ss, err := service.CreateSpreadsheet(spreadsheet.Spreadsheet{
        Properties: spreadsheet.Properties{
            Title: "spreadsheet title",
        },
    })
    sheet, err := ss.SheetByIndex(0)
    service.ExpandSheet(sheet, 20, 10)
    row := 1
    column := 2
    sheet.Update(row, column, "hogehoge")
    sheet.Update(3, 2, "fugafuga")

    // Make sure call Synchronize to reflect the changes.
    err = sheet.Synchronize()
    checkError(err)
}

Here the error:

 go run main.go

Not sure if it's a bug or me doing a mistake. Thanks for help
