"QueryBuilder : Failed to capture the event processor_query.: no thrown error", from running CMDB Query Builder, or "Update Query Based Services" scheduled job - Known Error

"QueryBuilder : Failed to capture the event processor_query.: no thrown error", from running CMDB Query Builder, or "Update Query Based Services" scheduled job Description When running any CMDB Query the following Error can be seen in the system logs:

QueryBuilder : Failed to capture the event processor_query.: no thrown error This has been identified so far as not breaking the run of the query, and appears to be from code related to usage tracking.

Each run of the "Update Query Based Services" scheduled job may also cause many thousands of this error as it updates all service CIs that are based on queries.

Steps to Reproduce

Use a Developer Instance (Quebec/Paris) 1. Create an Query through CMDB Query Builder 2. Select Service as Starting Node. 3. Select Hardware as target Class. 4. Select ANY Relationship type between these classes. 5. Save + Run the Query. 6. Look into the System log, there should be Errors from the query builder reading the below QueryBuilder : Failed to capture the event processor_query.: no thrown error

If these queries are then used in a Query Based Service, the app node localhost logs will show something like this:
