There are cases where we are not able get a plan from the cache (ex. sqlserver evicted the relevant plan to free up memory). When this happens, we still submit a plan event with a plan signature but no plan definition. When querying for plans this is a bit weird since we say we've collected a plan because we see a plan event with a plan signature but we don't have the actual plan to show the user.
I see a few options here:
This PR is for option 1. We now won't see collection errors so I'm logging them instead but not sure what best practice is here.
