# Pull Request Template ## Description Fixes [CW-4330](https://linear.app/chatwoot/issue/CW-4330/bug-attachments-in-gallery-view-gets-duplicated-when-you-navigate-back) **Cause** When navigating back to a previously viewed conversation, attachments were being duplicated in the Gallery View. This occurred because the `SET_ALL_ATTACHMENTS` mutation was appending new attachments to existing ones `(attachments.push(...data))` instead of replacing them. Each time a user returned to a conversation, the attachment list would grow, showing duplicate images. **Solution** Updated the `SET_ALL_ATTACHMENTS` mutation to replace the entire attachments array instead of appending to it. This change ensures attachments are cleared before adding new ones when returning to a previously viewed conversation, preventing duplicates. ## Type of change - [x] Bug fix (non-breaking change which fixes an issue) ## How Has This Been Tested? ### Loom video https://www.loom.com/share/b2472c07e95843f6879724b19ef89311?sid=eed42238-b4bc-4dbe-8ede-a25a13b4610d ## Checklist: - [x] My code follows the style guidelines of this project - [x] I have performed a self-review of my code - [ ] I have commented on my code, particularly in hard-to-understand areas - [ ] I have made corresponding changes to the documentation - [x] My changes generate no new warnings - [ ] I have added tests that prove my fix is effective or that my feature works - [x] New and existing unit tests pass locally with my changes - [ ] Any dependent changes have been merged and published in downstream modules
