# Bug Report --- ## Bug Title Upload Button Unresponsive and Grayed Out When Adding Jewelry Images to Product Catalog --- ## Environment | Field | Details | |---|---| | **Platform** | TikTok Shop Assistant | | **Feature** | Product Upload / Catalog Management | | **Device** | Chromebook | | **Operating System** | Chrome OS | | **Browser** | Google Chrome (Chromebook default) | | **User Action** | Adding new jewelry product images to catalog | --- ## Steps to Reproduce 1. Log in to TikTok Shop Assistant with a valid seller account. 2. Navigate to **Product Catalog** or **Add New Product**. 3. Fill in or skip to the product image upload section. 4. Attempt to select or drag-and-drop jewelry images into the upload area. 5. Observe the state of the **Upload** button. --- ## Expected Result The **Upload** button should be fully active, clickable, and responsive, allowing the seller to select and upload one or more jewelry images to the product catalog without obstruction. --- ## Actual Result The **Upload** button is completely **unresponsive and visually grayed out**, preventing any image from being uploaded. No error message or tooltip is displayed to indicate why the button is disabled or how to resolve the issue. --- ## Severity **High** > The upload function is a core workflow step for catalog management. Its complete failure blocks sellers from listing or updating products, directly impacting business operations and revenue generation. It does not constitute **Critical** severity only because existing listings remain unaffected; however, new product creation is entirely halted. --- ## Possible Technical Cause - **Chrome OS / Browser Compatibility Issue:** The file picker API or a JavaScript event listener tied to the Upload button may not be fully compatible with Chrome OS or a specific version of Chrome, causing the button to render in a permanently disabled state. - **Missing or Unsatisfied Pre-conditions:** Front-end validation logic may be silently requiring a mandatory field (e.g., product title, category, or SKU) to be completed before enabling the button, with no visible indicator communicating this dependency to the user. - **File Type / MIME Validation Failure:** The component may be pre-validating accepted file types on initialization and failing silently on Chrome OS, disabling the button as a fallback. - **JavaScript Runtime Error:** A JS exception during component initialization may be leaving the button in its default `disabled` state without executing the enable logic. - **Session or Permission Scope Issue:** The authenticated user session may lack the required seller permissions or role scope to perform catalog uploads, causing the UI to disable the control without surfacing a meaningful error.
