Update to `next`15 / `react`19 causes type errors in the console

[pepew-le-boss]

I've updated my next project to the version 15 coming with react version 19.

But now when I build the app and run it, I get 2 different type errors in the console:

1. [TypeError: Cannot read properties of undefined (reading 'isDynamic')]
2. [Error: failed to pipe response] { [cause]: [TypeError: readable.pipeTo is not a function] }

I can still build the app, still use the app and still use the cache, basically everything is working fine.
But these two errors are spammed in the console every time I navigate or do actions on the website.

Because I pay the log usage once the app is deployed, this bug is major for me.

I'm almost certain the bug come from this library because when I don't use this cache and fallback to the next cache, these errors are not logged anymore.

Environment:

• OS: Windows
• Node.js version: 18.18.0
• @neshca/cache-handler version: 1.9.0
• next version: 15.1.4

Having the same issue, the only difference is that I get 500 Internal Server errors when navigating to any page on my app.

Using a custom implementation that uses S3 as the data store, with a fallback LRU cache.

Removing all code related to the cache handler in next.config.ts gets rid of the 500s.

We've faced with the same issue with @ViktorShev and saw the requirements on npm (not compatible with next 15). Downgrading next version to 14 resolved the issue

We have also downgraded to Nextjs 14.2 because @neshca/cache-handler@1.9.0 is not compatible with Nextjs 15 or higher

Any updates on this? I’ve seen there is a pull request, but there hasn’t been an update since February.

#969

As it seems this plugin is not actively maintained anymore we created a new improved redis cache handler for next.js 15. It uses redis keyevent notifications to fix this issue. Besides that I implemented a couple of other performance optimizations by eliminating the resource hungry hscan and including some in-memory caching synced via keyspace notification (so it is multi node capable).

For anyone landing here from search engines.

This package has not been updated since Next 14 was latest. Next 15 introduced a lot of breaking changes in caching. You cannot just expect it to work after upgrading to Next 15/16.

Alternatively you can use this package https://github.com/fortedigital/nextjs-cache-handler which offers a seamless transition as it's based on @neshca/cache-handler rather then written from scratch with a completely different API. It's good to have options :)
