A typical error we see when trying to update the instrumentation config CR is:

2024-11-12T08:43:28Z ERROR error updating instrumentation config {"controller": "instrumentor-instrumentationconfig-instrumentedapplication", "controllerGroup": "odigos.io", "controllerKind": "InstrumentedApplication", "InstrumentedApplication": {"name":"deployment-pricing","namespace":"simple-demo19"}, "namespace": "simple-demo19", "name": "deployment-pricing", "reconcileID": "8c980fc2-ead9-47c7-b2ac-69be6e880002", "workload": "deployment-pricing", "error": "Operation cannot be fulfilled on instrumentationconfigs.odigos.io "deployment-pricing": the object has been modified; please apply your changes to the latest version and try again"}

This is due to the Get and Update pattern we use. Following #1710 , use the update error util for this case as well.
Adding to the error handling util - a check for IsNotFound error and ignoring it.

can a list operation return not found? or is it only for safety?

If it's not found, don't we want to return and not cause any updates?
