We are aware of an issue that is causing 1Password Cloud Connector integrations to display errors in the app and to send error notifications to some users even when logging is working as expected. We have determined that connectors showing "Error: EXTERNAL_ERROR_CLIENT_ERROR_RESPONSE" are receiving logs, meaning the integrations are healthy, and users do not need to take any action on those connectors. We are working on a fix so that false errors are not shown when logs are being received.
If you see the above error in your account for a 1Password Cloud Connector, you can verify that logs are being received by viewing the latest 1Password logs in Report Builder.
