Hi @mmakara2021 - great question, unfortunately there is not currently a built-in way to log Set and Map. In v4.3.0, I added support for List<SObject>, but I still have not implemented support for Set or Map yet. I've created issue #222 to add this functionality for Set<SObject> and Map<Id, SObject> in a future release - in the meantime, you can try these workarounds:

// Workaround for logging a Set<SObject>
Set<SObject> someRecordSet = new Set<SObject>();
Logger.info('logging a set by converting to a list', new List<SObject>(someRecordSet));

// Workaround for logging a Map<Id, SObject>
Map<Id, SObject> someRecordMap = new Map<Id, SObject>();
Logger.info('logging a set by converting to a list', new List<SObject>(someRecordMap?.keySet()));

For the map it does not work giving me error:
Error:(56, 69) Invalid initializer type Set found for List: expected an Integer or a List of type SObject

@mmakara2021 sorry about that! I had 1 mistake in my original answer - it should use the values() method, instead of keySet() method, on the Map. Here's the updated/corrected sample:

// Workaround for logging a Set<SObject>
Set<SObject> someRecordSet = new Set<SObject>();
Logger.info('logging a set by converting to a list', new List<SObject>(someRecordSet));

// Workaround for logging a Map<Id, SObject>
Map<Id, SObject> someRecordMap = new Map<Id, SObject>();
Logger.info('logging a set by converting to a list', new List<SObject>(someRecordMap?.values()));
