Data curator configuration: Encountered error prevents saving settings

When you configure the data curator component using the Production Management Data Curation Configuration tool, you encounter the following error message, but the Events to CONNECT log files don't indicate the cause.

This issue may occur if you set the data collection mode to HistoryOnly for a couple of days and then change it back to CurrentWithBackfill. Changing the mode removes the data ingress details partially, so when you run the configuration tool to repopulate the data ingress details, you may encounter this error.

Resolution

Restart the Events to CONNECT service.
