Creating TopicAssignment records silently fails in a managed package context

[jongpie]

The Logger and LogEntryEventBuilder methods for using Salesforce's Topics are not currently available in the managed package due to an issue with the functionality. New Topic records were successfully created, but the related TopicAssignment records for Log__c and LogEntry__c` were never inserted.

This functionality all works both when running in an org without a namespace (unpackaged code), as well as in a namespaced scratch org (using the same Nebula namespace, but silently fails in orgs that have installed the managed package.

Possible theories

• Some kind of permission issue with managed package + automated process user
• Maybe topic assignments should be created async (but still would not explain why this functionality works fine when running as unpackaged code/no namespace)
