FeatureAlreadyExistsException

Thrown when attempting to create a feature that already exists in the store.

This exception is thrown by FeatureStore.plusAssign() when trying to insert a feature with a UID that is already present in the store. To avoid this exception, either check existence first using FeatureStore.contains() or use the com.yonatankarp.ff4k.core.createOrUpdate extension function.

Example:

// Safe approach using createOrUpdate extension
featureStore.createOrUpdate(feature)

// Or check existence first
if (feature.uid !in featureStore) {
    featureStore += feature
}
