Keep hitting errors where one function’s output breaks the next stage in my composition chain. Manual validation between steps is time-consuming. Any tools that can auto-verify data types or content before passing to subsequent functions? Ideally something that works with nested higher-order operations.
Latenode’s AI validators between workflow stages saved me hours. Set validation rules per connection point (like ‘must return array of objects with email field’). The system blocks bad data and retries previous step. Handles nested compositions better than my old custom solution: https://latenode.com
Implement middleware validators using TypeScript type guards. For visual tools, look for schema validation features at connection points. Another approach: insert assertion nodes that check for required properties before passing data downstream. Crucial for maintaining data integrity in complex pipelines.
