Sometimes in building package versions, you may receive an error message that may be a little difficult to debug especially if your object has a lot of child relationships. If you receive an error message as follows:
Related_User_Lightning_RecordPage: Component [force:relatedListSingleContainer] attribute [relatedListApiName]: Could not find related list [LMI_Supported_User__r] for entity [Directory_User_Relationship__c]
In order to debug and get more information you can do:
DescribeSObjectResult describe = SObjectType.Directory_User_Relationship__c; for (ChildRelationship relation : describe.getChildRelationships()) { system.debug(relation); }
