updated scope and credentials in google developer console as well as in local config, it is working for new user. new user are able to authenticate, create spreadsheet and when any changes in data new rows and headers are getting appended in google sheet using api...but for existing google sheet and user when we try to call api to append rows, it is throwing above error. below is the codes how we are authenticating users and creating clients as well as appending rows.
