match_conditions must be a non-empty array

Error message

match_conditions must be a non-empty array

What it means

Argument-validation guard in the Parallel find-entities tool: 'match_conditions' is absent/not an array, or an explicitly empty array (the filter on non-empty arrays makes emptiness fail here too). The schema requires it as the third mandatory parameter defining what qualifies as a match. Malformed model call; nothing is sent to Parallel.

Solutions

1. Retry with 'match_conditions' as a non-empty array of condition objects/strings describing match criteria.
2. At least one condition is mandatory — an empty array cannot identify candidates.
3. Cross-check the schema's items definition for the expected condition shape.
