watsonx Orchestrate Developer Edition includes Langflow 1.10.0 by default. Langflow 1.10.0 automatically installs its own matching LFX (Langflow Runner), so you don’t need additional configuration. To run an older version of Langflow, install the version you want locally (outside ADK) from Langflow version history and specify the matching LFX version in your requirements.txt file before you import the flow into watsonx Orchestrate. Use this table to identify the correct LFX version for your Langflow flow:
Note:Flows you create with Langflow versions earlier than 1.7.0 may fail or behave unpredictably because these versions lack integrated LFX support. To ensure compatibility:
  1. Open the flow in the latest Langflow version. Use version 1.10.0 or later.
  2. Update deprecated or incompatible components.
  3. Export the flow again.
For Langflow 1.10.0, the system automatically installs the matching LFX runner. For older versions, add the correct LFX version to requirements.txt before you import the flow into watsonx Orchestrate.
