Hi @fiery spire. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

The error Console UnrecognizedActionError with a message like:

Server Action "0rtytyty5565yryry56565rgrte6464ryy" was not found on the server.

typically means that the client attempted to call a Server Action whose ID is no longer recognized by the server. This is often caused by a mismatch between the client and server code, usually after a new build or deployment. Some common causes for this issue locally include:

  1. Rebuilding Without Refreshing the Client:
    If you rebuild your Next.js app (e.g., run next build and next start) but keep your browser tab open without refreshing, the client may try to call a Server Action using an old ID that no longer exists in the new build. This is because Server Action IDs are regenerated on each build for security reasons, and the client-side JavaScript may be out of sync with the server-side code. This scenario is described in several issues, where users observe that after a rebuild, actions cannot be found until the page is refreshed Client cannot recover from version skew Error: Failed to find Server Action.

  2. Deleting the Build Cache:
    If you delete the .next directory (the build cache) and then rebuild, the server action IDs will change. If your client is still running code from the previous build, it will reference outdated action IDs Error: Failed to find Server Action.

  3. Conditional or Dynamic Imports/Exports:
    Issues with how server actions are imported or exported (such as using wildcard exports or re-exporting from barrel files) can sometimes cause actions to not be registered correctly, leading to this error Server actions regression in 14.2.8.

#

How to Fix Locally:

  • Always refresh your browser after rebuilding your Next.js app to ensure the client and server are in sync.
  • Avoid keeping old tabs open across builds.
  • If you are using custom exports for server actions, try switching from wildcard exports to named exports, as this has resolved similar issues for some users.
  • If you are using Docker or other build systems, ensure that the build cache is handled consistently between builds.

For more details, see the official Next.js documentation on this error:
[https://nextjs.org/docs/messages/failed-to-find-server-action](https://nextjs.org/docs/messages/failed-to-find-server-action)

If the problem persists even after following these steps, it may be related to a bug or regression in the Next.js version you are using, as discussed in the linked issues above. Upgrading to the latest stable version may help if you are on an older release.

Let me check the knowledge base for you again. Give me one moment! :books:

Based on the knowledge sources, there are several reports of issues where Server Actions or navigation behave differently between browsers, especially between Chrome and Firefox. For example:

  • There are known cases where errors or unexpected behaviors (such as hydration errors or navigation errors) only occur in Chrome but not in Firefox or Edge. In some cases, these issues are related to browser extensions, cache, or how Chrome handles certain requests or tab states Hydration error in fresh Next.js 15 app — Chrome only (Edge/Firefox work fine).
  • Some errors, like "Failed to find Server Action," can be triggered by client/server code mismatches, which may be exacerbated by Chrome's aggressive caching or tab suspension features. Users have reported that after a rebuild, Chrome may still use outdated client code, leading to these errors, while Firefox does not exhibit the same problem Server actions regression in 14.2.8.
  • There are also reports that Chrome's handling of inactive tabs or network suspension can cause issues with hot reloading or server communication, which may not be present in Firefox Hot reloading stops working after sleep/resume device on Chrome, but not Firefox.

What you can try:

  • Hard refresh (Ctrl+Shift+R or Cmd+Shift+R) in Chrome to clear the cache and ensure the client is using the latest code.
  • Disable browser extensions in Chrome, as some extensions can interfere with page rendering or requests.
  • Make sure you do not have multiple tabs open with different versions of your app.
  • If you are using hot reloading or dev mode, try restarting your dev server and closing/reopening Chrome tabs.
#

If the issue persists only in Chrome and not in Firefox, it may be due to Chrome-specific caching or extension interference, as seen in the issues above. If none of these steps resolve the problem, it could be a Next.js bug that manifests only in Chrome, and you may want to follow or open an issue with a minimal reproduction for further investigation.

Let me know if you need more specific troubleshooting steps!
