Could not find related list [X] for entity [X]

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);
}
