Missing required parameter: urls

Error message

Missing required parameter: urls

What it means

Argument-validation guard in the Parallel extract/contents tool's execute: 'urls' is missing or not an array (args.get("urls").and_then(as_array) fails). The tool's schema has only urls in its required list, so this indicates the model called the tool without the URL list or with a wrong-typed value.

Solutions

1. Re-issue the call with 'urls' as a non-empty array of URL strings.
2. Validate each entry is a well-formed absolute URL before sending.
3. If the model intended a single page, pass it as a one-element array.
