Missing required parameter: processor

Error message

Missing required parameter: processor

What it means

Argument-validation guard in the same processor tool, immediately after the input check: 'processor' is absent or not a string (and_then(as_str) fails). The schema requires [input, processor] with processor naming which Parallel processor to run. Nothing has been dispatched yet; the error is returned to the calling model as a normal retryable tool failure.

Solutions

1. Retry including 'processor' as a string naming a valid Parallel processor.
2. Consult the tool schema/description for the accepted processor identifiers.
3. Ensure the value is a plain string, not a nested object or enum wrapper.
