Antigravity cloud-code request is missing a model id

Error message

Antigravity cloud-code request is missing a model id

What it means

The cloud-code request builder trims `request.model` and requires a non-empty result before constructing the JSON body. An empty or whitespace model id means the wire body would carry no model, which cloud-code cannot route, so the builder fails locally. This is the last structural check before the request JSON is assembled.

Solutions

  1. Set an explicit model id in the provider/session config for the antigravity route
  2. Verify default-model resolution produces a non-empty id before the session starts
  3. Fail early at session creation with a clear config error instead of at request time

Example fix

// before
provider.model = ""; // -> bail at request build time

// after
provider.model = "gemini-2.5-pro";
anyhow::ensure!(!provider.model.trim().is_empty(), "antigravity provider needs a model id");
Defensive patterns

Strategy: validation

Validate before calling

anyhow::ensure!(
    !request.model.trim().is_empty(),
    "antigravity request needs a model id; check provider config"
);

Type guard

fn model_id_present(model: &str) -> bool {
    !model.trim().is_empty()
}

Try / catch

match client.create_message_stream(request).await {
    Ok(s) => Ok(s),
    Err(err) if err.to_string().contains("missing a model id") => {
        Err(fix_config_and_restart()) // config-level fix, not a retry
    }
    Err(err) => Err(err),
}

Prevention

When it happens

Trigger: `request.model` is an empty string or only whitespace when the builder runs on an antigravity route.

Common situations: Provider config missing a `model` field; default-model resolution returning an empty string silently; a session created without a model after a config refactor.
