    IActorTest,
    IActorRdfMetadataExtractOutput,
    undefined,
>

The bus this actor subscribes to.

OptionalbusFailMessage

busFailMessage?: string

The message that will be configured in the bus for reporting failures.

This message may be a template string that contains references to the executed action. For example, the following templated string is allowed: "RDF dereferencing failed: no actors could handle ${action.handle.mediaType}"

name

name: string

The name for this actor.

Default
