Yesterday I deployed my Next.js application on AWS using sts (not amplify because it has cache problem and it was slow because and my application is e-commerce so needs fast as much as possible).

The website has been running well and everything looks fine except for a few pages that have many images.

Every image is optimized for better performance so we have proper caching. Everything is working fine on the caching side as well.

However, sometimes I see that my application receives 429 from /next/images* origin with message:

{“Reason”:”ConcurrentInvocationLimitExceeded”,”Type”:”User”,”message”:”Rate Exceeded.”}

I am confused what whether I should ask AWS to increase the limit. I do not have Developer Support here.

You can try my application here as well: https://dtjlmuofdvydq.cloudfront.net

A page that has issues: https://dtjlmuofdvydq.cloudfront.net/bachelorette-decorations

I tried asking for help on AWS support (basic not helping).

I tried configuring and changing default settings that comes with sts (enabling and disabling Cloudflare function) but still have the issue.

Amplify is not a solution here because of lack of control and speed.
