How does Backstage discover entities from a registered location?

It requires manual entry of each entity into the catalog

It uses a webhook to receive entity updates in real time

It only discovers entities when the location is first registered

It periodically scans the location for changes and ingests any new or updated entities

When registering a new entity location through the Backstage UI, what information must you provide?

The database connection string for the catalog

The target URL of the entity descriptor file

The full YAML content of the entity

What happens when Backstage processes a registered location that contains multiple entity descriptor files?

It reads each descriptor file and adds all defined entities to the catalog

It merges all entities into a single entity

It ignores any additional files and only processes the main catalog-info.yaml

It only processes the first descriptor file it finds

A user tries to register a location via the UI with the URL https://example.com/catalog/team.yaml. The registration fails with an error: 'Entity has an invalid kind'. The user opens the URL in a browser and sees the YAML content. What is the most likely cause of the error?

The URL is not accessible from the Backstage server.

The location type is set to 'file' instead of 'url'.

The YAML file contains a kind that is not recognized by Backstage, such as 'Service' instead of 'Component'.

The YAML file is not properly formatted.
