[Error] handling API request on metadata scan.

[zerobutsugar]

Running the metadata scan triggers the following error for some files, but the verbose logs don't identify which files are responsible:

[Error] [WebAPI] Error handling API request '/API/EditModelMetadata' for user 'local': Internal exception: System.NullReferenceException: Object reference not set to an instance of an object.
at SwarmUI.WebAPI.ModelsAPI.EditModelMetadata(Session session, String model, String title, String author, String type, String description, Int32 standard_width, Int32 standard_height, String usage_hint, String date, String license, String trigger_phrase, String prediction_type, String tags, String preview_image, String preview_image_metadata, Boolean is_negative_embedding, String subtype) in /SwarmUI/src/WebAPI/ModelsAPI.cs:line 504
at SwarmUI.WebAPI.API.HandleAsyncRequest(HttpContext context) in /SwarmUI/src/WebAPI/API.cs:line 134

This leaves the Scan UI in a broken state (stuck "Running", incorrect remaining count like -2), requiring an application restart to recover the scan function.

My theory is you had a model scanned and set for metadata update, where the only available previews on civitai were videos, and Swarm bugged out not being able to imageify a video. If that's accurately the case, it should be fixed now (it will simply not be able to apply the preview image in this case, but otherwise work as intended).
