📝 WalkthroughWalkthroughThe pull request adds image-upscaling, virtual try-on, SVG generation, and Q4 video-generation nodes. It updates Gemini Nano Banana model options, pricing, and request routing. It also updates Vidu task failure handling, the project version, and the workflow templates pin. Priority: ➖ Normal Estimated code review effort: Merge Risk: 🔵 Low · up to The new nodes mostly work, but a few edge cases can fail confusingly or hang: extra batched images are silently ignored, a stalled upscale download can wait indefinitely, and Kling API errors or very wide images can fail without a clear message. Fix these before or shortly after merge; none are broadly blocking. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new workflows reuse established authentication and upload controls. No introduced security vulnerability was established, but service-side asset ownership, result handling and interrupted-task cleanup remain unverified.

Learning: In ComfyUI node implementations under `comfy_api_nodes/`, when building JSONata expressions that use `IO.PriceBadge` for `$lookup` against a price map keyed in lowercase, do not add an explicit `$lowercase()` around widget values (e.g., combo options like "1K", "2K", "4K"). The ComfyUI frontend automatically lowercases widget values before evaluating the JSONata expression, so the lookup keys will already match the lowercase map entries.

Learning: In Python partner API nodes under comfy_api_nodes/, keep each node’s execute body self-contained, including input validation and the submit → poll → status-check → download flow. Do not extract duplicated validation into shared helpers when limits are endpoint-specific or model-version-specific, because vendor constraints may diverge; preserve per-node readability, independent editability, and a limited blast radius.

Learning: In `comfy_api_nodes` Python async node implementations (e.g., `async def execute`), synchronous CPU/IO-heavy helpers (such as video/audio trim/resize and base64/MP3 conversion) may be called directly without offloading to a thread executor (e.g., `asyncio.to_thread`). Treat this as an existing, broader refactor concern rather than a new PR regression: if the PR does not introduce additional synchronous blocking calls, reviewers should not flag it as a new issue. However, if the PR adds new synchronous CPU/IO work inside `async def execute`, prefer offloading with `asyncio.to_thread` (or an equivalent background executor) to avoid blocking the event loop.

Learning: In the `comfy_api_nodes/` package, partner/API node `execute` implementations should keep the full submit → poll → status-check → download flow written inline within each node (even if similar logic appears across multiple nodes). This is an intentional repo convention to optimize per-node readability and independent editability, so during reviews you should generally not recommend refactoring this pattern into a shared helper function for these nodes (unless there’s a concrete correctness/security issue).

Learning: When consuming dictionaries produced by IO.Autogrow.Type, rely on their iteration order to match the configured template-slot order. This ordering is preserved by _expand_schema_for_dynamic, parse_class_inputs, and build_nested_inputs, so consumers should iterate the dictionary directly when processing dynamic slots.

Set a timeout for the result download.
If the image server stops sending data after the task completes, download_url_to_image_tensor can wait indefinitely. Its default timeout=None creates an HTTP client without a total deadline. Pass a timeout that accommodates large upscaled images so the workflow fails instead of waiting for manual cancellation. (raw.githubusercontent.com)

Preserve the minimum image size when downscaling.
Kling requires each image’s shortest side to exceed 300 pixels. A 4096×600 garment or person image becomes 2048×300 here, so Kling rejects it after upload. Adjust the image at this boundary to satisfy both size limits. An image already below the minimum needs the same treatment. (kling.ai)

Check the create response before polling.
KlingSolutionCreateResponse.data is optional. When the proxy returns a successful HTTP response with a nonzero Kling code and no task data, response.data.task_id raises AttributeError instead of reporting the API message. Check the response code and data.task_id before calling poll_op.

Reject batched start frames instead of dropping the extra images without a message.
upload_image_to_comfyapi sends only the first image of a batch because it calls upload_images_to_comfyapi with max_images=1. If a user connects a batch, the node uploads frame 0 and ignores the other frames. The user gets no message about this. The other image-to-video nodes in this file (ViduImageToVideoNode, Vidu2ImageToVideoNode) raise ValueError("Only one input image is allowed.") in this case. Add the same check here.
