Thank you for your understanding and contribution!
@ss958 commented on GitHub (Sep 14, 2025):
I am using the latest versions of Dify and ComfyUI. I followed the plugin instructions to export the ComfyUI API for use, which resulted in this error. I noticed that the API JSON data exported by the current latest version of ComfyUI is inconsistent with the ComfyUI-related section in the Dify documentation. Please verify and fix this issue.
@dosubot[bot] commented on GitHub (Sep 14, 2025):
@crazywoola, the user reports that the latest ComfyUI API JSON export is inconsistent with the Dify documentation, causing a KeyError related to the missing 'nodes' key. Could you please help verify and address this issue?
