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)

  1. Open OS > Pipelines > Graph and select a pipeline.
  2. Click Warnings in the graph header.
  3. Review the warnings list.
  4. Select a warning to focus the corresponding node/port in the canvas (when a node id is present).
  5. 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.
