To help 'Song' with the API error messages encountered, here are some steps and considerations based on the documentation and API references:
Check API Quotas: Ensure that your algorithm is within the plotting quotas. Exceeding these can cause errors in retrieving backtest charts. The quotas depend on your organization tier, with limits on the number of series and data points per series. For example, the Free tier allows up to 10 series and 4,000 data points per series.
Inspect Algorithm Code: Verify that the algorithm correctly implements the
get_chart_updatesmethod. This method fetches chart updates since the last request. Ensure that your code is not making excessive or unnecessary calls to this method.Review Error Handling: Use the
errormethod in theAlgorithmPythonWrapperclass to log detailed error messages. This will help in debugging and understanding the issue more clearly.Implement a Retry Mechanism: Consider adding a retry mechanism to handle temporary API failures. This can involve waiting for a short period before attempting to fetch data again.
Check Network Stability: Ensure that your network connection is stable. Intermittent connectivity issues can lead to API errors.
Consult Documentation: Review the QuantConnect documentation for any updates or known issues related to API endpoints for backtest charts and orders.
Contact Support: If the issue persists, reach out to QuantConnect support for assistance. Provide them with detailed logs and error messages for further investigation.
By following these steps, you can address the API error messages and improve the reliability of your algorithm's interaction with the QuantConnect platform.

Hi Song Yang ,
The Eng Team has solved this issue, and I can no longer reproduce it.
Please let us know if it persists on your end.
Best regards,
Alex
