Event generates error to EventRecord: getEventTarget() called with invalid record reference

An event may generate an error traced in the log with the originating reason, but the displayed message seems incorrect:

The record is there and is not deleted. There are events that do not have a state of "error" that call to the same record type in the same way.

• View the events for errors and get the sys_id of the record in the URI field of the event
• Go in to the daily log for the same day of the error and search by the sys_id
• Note the output log which states a record does not exist, when it actually does

This is expected behaviour caused by a temporary impersonation issue. If an impersonation is initiated but then not reversed back to the original impersonator, the user will be stuck in a bad state of impersonation. This can be observed by looking at the user that updated the event. If this is not system and is instead a user that does not have access to the instance record on the event, the event will output this error when processed. However, there is no platform code fix necessary.

In some situations, there might be a custom Business Rule that runs before - Insert and subsequently fires an event. This might cause a condition where the event is processed before that record is created, leading to the error.

In such event, it is recommended to implement the eventQueueScheduled() method to fire the event a minute into the future so that we can ensure the record is created first and the event is successfully processed.
