Missing required parameter: search_queries

Error message

Missing required parameter: search_queries

What it means

Argument-validation guard in the Parallel search tool's execute: 'search_queries' is absent or not a JSON array (and_then(as_array) yields None). The schema requires it alongside objective. Fires when the calling model omits the field or passes a string/object instead of an array of strings.

Solutions

1. Retry with 'search_queries' as an array of query strings (e.g. ["rust async runtime"]).
2. If a single query was intended, wrap it in a one-element array.
3. Check the advertised JSON schema to remind the model of the array type.
