No IBKR ConID Error caused Strategy not to complete

Technical Help
#1

A couple of my strategies received errors this morning and the strategy orders did not complete. I received the below error:

2025-08-11 09:33:43 quantrocket.zipline: ERROR requests.exceptions.HTTPError: ('400 Client Error: BAD REQUEST for url: http://houston/blotter/orders', {'status': 'error', 'msg': 'No IBKR ConId found for Sid FIBBG00L1KN476, is the Sid valid and did you collect the security listing from IBKR?'})

I checked in the Data Browser for the USStock-1min and the sid / symbol does exist. Does this mean IBKR does not allow trading this symbol?

The blotter periodically queries the master service for a mapping of sids to IBKR conids. This mapping lets the blotter take an order for a sid and send the corresponding conid to IBKR. The error means the blotter had no conid for this sid.

Check the securities master record and confirm the ibkr_ConId field is populated. This sid should have a conid (it does on my system), so verify it on yours. If it’s missing, collect the security from IBKR to populate it. You can then submit a manual, non-marketable order for this security to the blotter to confirm the fix without waiting for your strategy to run again.
