Missing required parameter: input

Error message

Missing required parameter: input

What it means

Argument-validation guard in the Parallel processor/task tool's execute: 'input' is missing entirely (args.get("input") yields None — any JSON type is accepted, only presence is checked). The schema requires [input, processor]. Malformed model call; returned as a tool error before any work is dispatched.

Solutions

1. Re-issue the call including 'input' (string or structured payload to be processed).
2. Pair it with the required 'processor' parameter per the schema.
3. Check that argument serialization is not silently dropping null/omitted fields.
