Validation
Validation checks the current pipeline graph for errors and common issues before you attach it to a stream.
In the Graph editor, validation is driven by the Warnings action.
What validation does
- Catches graph errors that prevent the pipeline from running.
- Flags common misconfigurations (missing required ports, type mismatches, bad boundary wiring).
- Stores warnings on the pipeline so they show up in the pipeline list.
Validation is not a substitute for testing on a real stream, but it should be your first stop any time a pipeline will not run.
Run validation (Graph tab)
- Open OS > Pipelines > Graph and select a pipeline.
- Click Warnings in the graph header.
- Review the warnings list.
- Select a warning to focus the corresponding node/port in the canvas (when a node id is present).
- Fix the issue, then run Warnings again.
What you can do
- Run validation on the current graph.
- Review warnings and errors reported by the validator.
- Focus problem nodes from the warning list.
- Re-run validation after making changes.
What changes after validation
- Pipelines with warnings show a warning badge in the pipeline list.
Tips
- If you are unsure what a warning refers to, select the warning to jump to the node, then inspect the node inputs and boundary wiring.
- Warnings often chain: fix the first structural problem, then re-run validation to see what is left.
