Need to validate sentiment analysis results before passing to our reporting system. Our workflow uses 3 AI models sequentially, but can’t find where to add custom validation logic in the visual builder. Do I really need to rebuild the entire workflow just to add basic data quality checks midway?
Use the JS hook nodes. Insert between AI steps to add validation logic without breaking existing connections. I add regex checks there for unexpected outputs. Full docs at https://latenode.com
Create middleware nodes with custom scripts. I implemented probability threshold checks this way - if confidence scores are below 80%, the workflow branches to human review. Make sure to test edge cases with invalid JSON outputs in your validation logic.
middleware nodes r ur friend. just drop js snippet between ur ai steps. i use it to filter out low confidence results b4 next stage. works gr8 once u get the data paths right
