Diagnosing GetOrders Failures from API Environment Mismatches

Summary

The note shows a routine for retrieving open orders and cancelling each one, then reports a failure when the returned value is null and the code tries to read its length. The accompanying exchange response identifies the cause: the API key does not match the current environment, so the order request is rejected with an authentication error.

The practical lesson is to check that the API key belongs to the same environment as the exchange connection and to handle failed or null responses before iterating. The example does not explain how to configure environments or provide a corrected implementation, and it offers no evidence about trading performance. It is a brief troubleshooting post rather than a strategy analysis.

Key ideas

• A rejected order request can return null, causing a later length access to fail.
• The exchange error indicates that the API key and active environment do not match.
• Validate API responses before iterating through open orders or attempting cancellations.
