> camel-jbang - camel ask returns 404 when using Vertex AI endpoint

> Key: CAMEL-23728
> URL: https://issues.apache.org/jira/browse/CAMEL-23728
> Project: Camel
> Issue Type: Bug
> Components: camel-jbang
> Reporter: Guillaume Nodet
> Assignee: Guillaume Nodet
> Priority: Major
> Fix For: 4.x

>
> When using `camel ask` through Google Cloud Vertex AI, the LLM client sends
> the model name as-is (e.g., `claude-sonnet-4-6`) in the Vertex AI URL path:
> {code}
> /v1/projects/<project>/locations/global/publishers/anthropic/models/claude-sonnet-4-6:rawPredict
> {code}
> This returns a 404 because Vertex AI expects a versioned model identifier
> (e.g., `claude-sonnet-4-6@20250514`).
> The HTML error response from Google is dumped directly to the terminal:
> {code}
> LLM returned status: 404
> <!DOCTYPE html>
> <html lang=en>
> ...
> <p><b>404.</b> <ins>That's an error.</ins>
> <p>The requested URL <code>/.../models/claude-sonnet-4-6:rawPredict</code>
> was not found on this server.
> {code}
> Two issues:
> 1. *Model name mapping* — LlmClient should map model names to Vertex
> AI-compatible identifiers when the endpoint is a Vertex AI URL
> 2. *Error handling* — Non-JSON error responses (like HTML 404 pages) should
> be parsed gracefully instead of dumping raw HTML to the user
> *Workaround*: Use the Anthropic API directly with `--api-type=anthropic
> --api-key=$ANTHROPIC_API_KEY`
