openclaw - 💡(How to fix) Fix [Bug]: StepFun (stepfun-plan) plugin does not register image generation provider — image_generate silently fails [1 pull requests]

Bug type

Regression (worked before, now fails)

Beta release blocker

No

Summary

The StepFun plugin (extensions/stepfun/provider-catalog.ts) registers itself only as a text model provider via api.registerProvider(), but never calls api.registerImageGenerationProvider(). As a result, when users configure imageGenerationModel.primary: "stepfun-plan/step-image-edit-2", the image_generate tool silently fails because getImageGenerationProvider("stepfun-plan", cfg) returns undefined.

Steps to reproduce

1.Configure StepFun API keys and provider 2.Set imageGenerationModel.primary: "stepfun-plan/step-image-edit-2" 3.Call image_generate — task starts (returns task ID) but never completes 4.Background image generation task fails silently

Expected behavior

StepFun does have image generation API endpoints (e.g. /step_plan/v1/images/generations for step-image-edit-2). The plugin should register itself as an image generation provider so that image_generate can route requests to it.

Actual behavior

In extensions/stepfun/provider-catalog.ts, the register() method does: api.registerProvider({ id: "stepfun", ... }); api.registerProvider({ id: "stepfun-plan", ... });

But never calls: api.registerImageGenerationProvider({ id: "stepfun-plan", ... }); The list of registered image generation providers in OpenClaw includes: openai, google, deepinfra, xai, litellm, vydra, comfy, minimax, openrouter — but not stepfun or stepfun-plan.
