[Bug]: Agent images frequently broken when using S3 CDN #10145
Description
What happened?
I'm using the S3 CDN. When I upload an agent image, the generated signed S3 URL is broken in some parts of the UI.
Version Information
0.8.0-RC4
Steps to Reproduce
Config.yaml
fileStrategy: "s3"
Env Vars
AWS_REGION=us-east-1
AWS_BUCKET_NAME=librechat-cdn-bucket
- Upload an agent image
- Wait a little while
- Reload the page
Expected: Agent images render in the model dropdown and the model chat.
Actual: Agent images are broken due to expired signed S3 image hrefs. Manually refreshing the page a few times fixes the issue for a short while.
What browsers are you seeing the problem on?
Chrome
