Users reporting that when they try to send multiple photos (more than 10) to Gus for lawn diagnosis, the chat fails with

an error message. This is particularly problematic when users want to show different angles of a plant disease or lawn issue.

User Impact:

- Chat fails when sending 10+ images at once

- Users have to delete photos and resend with fewer images

- Makes it difficult to get comprehensive lawn advice when multiple views are needed

- Error appears after images upload successfully, which is confusing

Steps to Reproduce:

1. Open chat with Gus

2. Attach 11 or more photos

3. Type a message (e.g., "What's wrong with these flowers?")

4. Send message

5. Chat fails with error
