when generating video from an image, I encountered an error: "An error occurred in the plugin, please contact the author of langgenius/comfyui/comfyui for help, error type: Exception, error details: Failed to convert Workflow to API ready. WanImageToVideo not found in widgets_value_names." The log information in dify is: api-1 | 2025-11-04 11:03:02.233 ERROR [Dummy-370] [base.py:211] - Error in stream response for plugin {'code': -500, 'message': '{"message":"{\"args\":{},\"error_type\":\"Exception\",\"message\":\"Failed to convert Workflow to API ready.

Any assistance would be greatly appreciated. I can run this workflow in the Comfyui web interface.

Hi @yangbig730! I'm Dosu and I’m helping the dify team.

The error happens because the Dify ComfyUI plugin only recognizes nodes listed in its static config file, widgets_value_names.json. The node type WanImageToVideo is missing from this file, so the plugin can't convert your workflow for API execution—even though it works in the ComfyUI web UI, which doesn't have this restriction.

To fix this, you need to add an entry for WanImageToVideo to widgets_value_names.json with the correct widget input names. Based on your workflow and similar nodes, the entry should look like:

"WanImageToVideo": [
    "width",
    "height",
    "length",
    "batch_size"
]

Add this to the JSON object in widgets_value_names.json (usually found at tools/comfyui/tools/json/widgets_value_names.json in the plugin code). Make sure the order of the names matches the order of values in your workflow's widgets_values array for this node.

After updating the file, restart the plugin or the Dify service so the changes take effect. This should resolve the error and allow your workflow to run via the API/plugin integration as well as in the web UI.
