Account cannot access requested Service Instance.
- The requested Sync Service does not belong to this account.
- You have multiple accounts, and this Sync Service does not belong to the account whose credentials you used.
Confirm that you're using the correct credentials for this instance's account. This could mean:
- Make sure the Access Token specifies the correct Account SID
- Make sure that the Account SID + AuthToken pair you're using (for REST access) matches the correct account
- Make sure the API Key + API secret you're using (for REST access) belongs to the correct account.
