(devinxi) EISDIR: illegal operation on a directory, read

[gunnartorfis]

Which project does this relate to?

Start/Router

When running vite dev, I get the following two errors:

Update: I should've opened up two separate issues.

FIXED: Could not resolve "tanstack:server-fn-manifest

This has been fixed in the latest alpha.

✘ [ERROR] Could not resolve "tanstack:server-fn-manifest"

    ../../node_modules/.pnpm/@tanstack+start-server-core@1.120.4-alpha.21/node_modules/@tanstack/start-server-core/dist/esm/server-functions-handler.js:4:30:

        ╵                               ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  You can mark the path "tanstack:server-fn-manifest" as external to exclude it from the bundle,
  which will remove this error and leave the unresolved path in the bundle.

Same issue for me (but no error in the route generation).

Just an FYI, I tried out the latest alpha release and this is still broken.

Same error on react-start alpha 14, also tested react-start alpha 15 as it was just released with same outcome, upon importing and using any query/mutation the error is logged.

[schiller-manuel]

@MikeT117 can you please provide a complete example that produces this error?

[gunnartorfis]

That tanstack:server-fn-manifest error is now gone @schiller-manuel in alpha.14.
But I still get that error from the plugin.js file. It is weird to me that it is referencing some Netlify stuff.

[gunnartorfis]

@schiller-manuel I modified the plugin.js file to add debug logs.
Not sure why it is treating the folder as a file 🤔 I added my route structure for reference here too.

[schiller-manuel]

@gunnartorfis can you share a complete example repo?

[gunnartorfis]

@schiller-manuel here's a link: https://github.com/gunnartorfis/tanstack-start-devinxi-repro

In case it is related to my env, I am on Node v22.15.0 and using pnpm 10.7.0.

[ajxbit]

This is happening for Cloudflare but if works for the default node-server preset

      tanstackStart({
        target: 'cloudflare_module',
      }),

[jofflin]

Any news on here? Maybe duplicate of #4195

[ajxbit]

@SeanCassiere any thoughts?
