To help Oliver with the issue of his backtest being stuck at launching on a paid node, here are some steps and considerations:
Check Node Status: Ensure that the B2-8 node (0b98f375) is active and not busy. This can be done by checking the node's status in the QuantConnect dashboard.
Review Recent Changes: Consider any recent changes made to the algorithm or project settings that might have affected the backtest process. This includes changes in data sources, algorithm logic, or configuration settings.
Inspect Logs: Look at the algorithm logs for any errors or warnings that might indicate why the backtest is not starting. Use logging statements within your algorithm to help trace any logic errors or unexpected behavior.
Restart Node: Try restarting the node to ensure it is not in a hung state and can properly execute the backtest.
Test with Different Node: If possible, switch to a different node to see if the issue is specific to the B2-8 node.
Contact Support: If the problem persists, reach out to QuantConnect support with details of the issue, including the node ID and any error messages.
Debugging Tools: Utilize the built-in debugger to step through your code line-by-line and inspect variables to understand the internal state of the program. This can help identify any runtime or logic errors.
Documentation Review: Consult QuantConnect documentation for any known issues or updates related to backtesting on paid nodes. This can provide insights into any recent changes or known bugs.
By following these steps, Oliver should be able to diagnose and potentially resolve the issue with his backtest. If further assistance is needed, contacting QuantConnect support would be a prudent step.
