KV PUT failed: 429 Too Many Requests

What is the issue or error you’re encountering

Were any changes to your rate limit policy for workers KV store. On 6th of November we started to experience multiple KV PUT failed: 429 Too Many Requests errors. As we havent deployed any changes related to that logic on our side I suspect it might be some kind of change on Cloudflares side. We are using auth0-nextjs library which provides user session caching functionality and to do so it uses Cloudflares KV store.

What steps have you taken to resolve the issue?

None yet, we will probably implement the retry with backoff

What are the steps to reproduce the issue?

Setup:

  1. Nextjs application
  2. Auth0-nextjs package installed and configured to store users session in KV
  3. When firing multiple requests, the auth0 package updates expiry timestamp in the KV store and triggers the put method on store instance.

I saw some update mentioned recently. No change in the policy itself. They’re just now strictly enforcing the 1 write-per-second-per-key listed here:
