Unknown

Represents a workflow node whose original implementation is not available in the current node registry.

Unknown is a compatibility placeholder. It appears when a workflow references a node type that the current app build cannot resolve from the active node registry.

This can happen when a workflow was imported from another version of Agentic WorkFlow, a custom node is missing, or an older workflow still contains a node that has been renamed or removed.

Do not add this node manually when building a new workflow. Use it as a signal that an imported or migrated workflow needs maintenance.

Replace it with the current node that performs the same job, then rerun the workflow from the previous known-good step.

SettingNotes
Target Node TypeThe unresolved node type the workflow was trying to load.

Unknown should not be treated as a reliable producer of workflow data. Any downstream node that depends on it should be reviewed after you replace the missing node.

  • No explicit credential or node dependency is declared in the node description.

An imported workflow contains:

flowchart LR
  Trigger["When Started"] --> Missing["Unknown"]
  Missing --> Next["Edit Fields"]

Open the Unknown node, check the target node type, then replace it with the current equivalent from the node reference. After replacement, inspect the output shape before keeping downstream mappings.

  • Confirm the workflow was created with the same app version you are using now.
  • Check whether the missing behavior now lives under In Page Action, Flow, Data Transformation, Core, AI, or Integrations.
  • If downstream mappings reference fields from the missing node, update those mappings after choosing the replacement.
  • If the node came from a custom extension or plugin, reinstall that dependency before running the workflow.
