artifact not found: %s, isInput=%t, Workflow Status=%+v

Error message

artifact not found: %s, isInput=%t, Workflow Status=%+v

What it means

The node was found but neither its inputs nor outputs contain an artifact with the requested name (isInput selects which map is searched). The message dumps the whole workflow status to help spot the mismatch between requested and actual artifact names.

Solutions

1. Check the exact artifact name via `argo get` on the node
2. Distinguish input vs output artifacts — artifacts declared under outputs are not in inputs
