YongJie-Xie opened a new issue, #1516: URL: https://github.com/apache/answer/issues/1516
## Describe the bug After upgrading from a previous version to Answer v2.0.0, attempting to upload an image triggers a runtime exception, and the upload fails. The browser console reports the error: `Cannot read properties of null`. ## To Reproduce Steps to reproduce the behavior: 1. Upgrade the Answer instance to version **2.0.0**. 2. Log in as a user. 3. Go to create a new Question or Answer. 4. Click the **Image Upload** icon in the editor toolbar. 5. Select an image file to upload. 6. See the error in the console and observe that the image does not appear. ## Expected behavior The image should upload successfully and display in the editor. ## Screenshots <img width="538" height="90" alt="Image" src="https://github.com/user-attachments/assets/da26717e-5a05-4344-8ed5-92c4ba57b78c"; /> ## Platform - Device: Desktop - OS: Windows - Browser: Chrome latest - Version: v2.0.0 --- ## Additional Context / Workaround **Workaround:** To temporarily fix this issue without redeploying: 1. Go to **Admin** > **Advanced** > **Files**. 2. Enter any text into `Authorized image extensions` and `Authorized attachment extensions`. 3. Click **Save**. 4. Delete the text from both fields (leave them empty). 5. Click **Save** again. **Root Cause Analysis:** The issue occurs because the API endpoint `/answer/api/v1/siteinfo` returns `null` for extension lists instead of an empty array `[]` after a fresh upgrade. **API Response (Error State):** ```json { "site_advanced": { "max_image_size": 0, "max_attachment_size": 0, "max_image_megapixel": 0, "authorized_image_extensions": null, "authorized_attachment_extensions": null } } ``` **API Response (After Workaround):** ```json { "site_advanced": { "max_image_size": 0, "max_attachment_size": 0, "max_image_megapixel": 0, "authorized_image_extensions": [], "authorized_attachment_extensions": [] } } ``` **Code Analysis:** The error is triggered in `src/components/Editor/hooks/useImageUpload.ts`. The code attempts to check `authorized_attachment_extensions.length > 0`. Since the value is `null`, accessing the `.length` property throws the exception. -- This is an automated message from the Apache Git Service.
