Based on the knowledge sources provided, there isn't specific information about a "socket hang up" error in relation to GrowthBook metrics. However, I can provide some general insights about metric-related errors in GrowthBook and potential troubleshooting steps: 1. Check your data source connection: Ensure that your data source (e.g., database) is properly connected and accessible. Connection issues can sometimes cause errors when trying to query metrics. 2. Verify query syntax: Make sure your metric queries are correctly formatted for your specific data source. 3. Examine server logs: Look for any error messages in your GrowthBook server logs that might provide more context about the "socket hang up" error. 4. Check for timeouts: The "socket hang up" error could potentially be related to a timeout issue. You may need to adjust timeout settings if your queries are taking too long to execute. 5. Verify network connectivity: Ensure there are no network issues between your GrowthBook instance and your data source. If the problem persists, you may want to: 1. Try rerunning the metric queries to see if it's a temporary issue. 2. Check if the error occurs for all metrics or just specific ones. 3. Verify if recent changes were made to your data source or network configuration. For more specific assistance, I recommend: 1.
