Unicorn Serialization Issue - Cannot perform initial serialization
Issue:
Version 4.1.5 | Options
Warning: your current predicate configuration for at least one configuration does not have any valid root items defined. Nothing will be serialized until valid root items to start serializing from can be resolved. Please review your predicate configuration.
There are dependencies between some configurations, therefore the order in which you sync them is important.
Configurations
Some configurations prevent the 'sync all' checkbox because they include predicates that rely on (currently) invalid root paths. You likely need to sync one or more base configurations.
Foundation.SerializationSitecore.Solution.Framework Root items DependentsThe following configurations depend on this one:
PredicatePredicates define which items are included or excluded in Unicorn. Serialization Preset PredicateDefines what to include in Unicorn based on XML configuration entries.
Target Data StoreDefines how items are serialized, for example to disk using YAML format. Serialization File System Data StoreStores serialized items on disk using the SFS tree format, where each root is a separate tree.
Source Data StoreDefines how source data is read to compare with serialized data. Normally this is a Sitecore data store. Sitecore Data StoreReads and writes data from a Sitecore database.
EvaluatorThe evaluator decides what to do when included items need updating, creation, or deletion. Serialized as Master EvaluatorTreats the items that are serialized as the master copy, and any changes whether newer or older are synced into the source data. This allows for all merging to occur in source control, and is the default way Unicorn behaves.
Initial SetupCannot perform initial serialization because the predicate configuration is including item paths which do not exist in the database. The following path(s) are invalid:
| |
MySitecoreSln.Feature.CustomCoreMenuMySitecoreSln.Feature.CustomCoreMenu Dep: 1This configuration's predicate cannot resolve all root items. This usually means the predicate is configured to rely on a parent item that does not exist in the Sitecore database. |
Reference
What is Sync?
Runs a synchronization operation, which will sync serialized items into Sitecore. The serialized state is merged into the database state, making additions, modifications, and deletions (in some cases) as needed.
Note: if you only need to sync part of a configuration, you can use the Update Tree command on the Developer tab of the Sitecore ribbon. When used on a Unicorn item, it performs a partial sync.
What is Reserialize?
This clears the serialized data and refills it with the items in the Sitecore database. This should be done if you add or remove items from your predicate after initial serialization.
Note: if you only need to reserialize part of a configuration, you can use the Dump Tree command on the Developer tab of the Sitecore ribbon. When used on a Unicorn item, it performs a partial reserialize.

Solution:
In my case, I was trying to serialize only one item in the Core db content. So, I got rid of the feature serialization extends and dependencies attributes in the feature serialization config since they were irrelevant to my case but, discretion is needed on a case to case basis. In a different scenario, I would ensure that the required items/folders are present in Sitecore or else, remove those totally from the Foundation.Serialization.config
