This error is because the HubSpot + WhatsApp integration Chrome extension you are using is out of date. To solve the problem:
- Remove the old HubSpot + WhatsApp integration extension from Google Web Store (version 3.4)
- Add the updated HubSpot + WhatsApp integration extension from Google Web Store (version 3.7 or higher)
You will not need to authorize your WhatsApp or HubSpot account after adding the new HubSpot + WhatsApp integration Google Chrome extension to your browser.
In case you were not logged into the HubSpot + WhatsApp integration or you were not logged into the Dashboard when you added the updated HubSpot + WhatsApp integration extension, please update your HubSpot account and sync / log into the Integration Dashboard from HubSpot + WhatsApp.
