Which of the following is a common error that occurs during entity ingestion in the Backstage catalog?

The entity descriptor contains a YAML syntax error, such as an unclosed bracket.

The entity descriptor is valid but the catalog refresh interval is set too high.

The entity descriptor uses a valid schema but references a non-existent parent entity.

The entity descriptor is valid but the entity kind is not registered in the catalog.

An entity references another entity by name, but the referenced entity does not exist in the catalog. What is the most likely result?

The referencing entity fails to ingest with a validation error.

The referencing entity is ingested, and the relationship is left unresolved.

The catalog refresh is paused until the referenced entity appears.

The referenced entity is automatically created from the reference.

A built-in catalog processor fails with the error: 'Entity has an invalid relation: ownedBy, target group:infrastructure'. The group entity `infrastructure` exists in the catalog. What is the most likely cause?

The group entity has no members.

The group entity has a `spec.type` field that is not 'group'.

The group entity is in a different namespace than the entity referencing it.

The entity referencing the group is not a component or system.

An entity in the catalog is not reflecting recent changes made to its source descriptor. What is the most likely cause?

The entity relationship is incorrect.

The entity descriptor has a syntax error.

The catalog location was deleted.

The catalog refresh interval has not elapsed since the change was made.
