Getting error "Subagent with name 'GoatWriter' not found in platform default-agent-platform." when running Java examples #77
Description
Something is wrong with the GoatWriter bean registration. From the /scripts/java directory I ran shell.sh. When the embabel shell came up I gave the command x "Tell me something intereseting". This eventually leads to the error Subagent with name 'GoatWriter' not found in platform default-agent-platform. Available agents: [BookWriter, FactChecker, Handoff, JavaStarNewsFinder, ReviseStoryUntilSatisfied, Subagents, SupportAgent, WikiAgent]
I think it has something to do with https://github.com/embabel/embabel-agent-examples/blob/main/examples-java/src/main/java/com/embabel/example/handoff/Subagents.java#L56, but I can't follow how that
