Vite example shows this error Could not POST streaming to /sync/stream in WebRemote.ts and 404 Not Found http://localhost:3020/sync/stream

When running example-vite pnpm dev with vite.config.ts:

server: {
   port: 3020,
},

The web seems working. But my browser shows this error:

Could not POST streaming to /sync/stream - 404 - Not Found: [WebRemote.ts:58:14](http://localhost:3020/@fs/Users/guillem/programacio/codi/cites/databases/powersync-js/packages/powersync-sdk-web/src/db/sync/WebRemote.ts)

And also XHR POST http://localhost:3020/sync/stream [HTTP/1.1 404 Not Found 1ms]

Do you know why?

I write the question here to be searchable in Google for others.

Hi @guillempuche this is currently expected behaviour.

The log above the error mentions that there aren't any actual backend credentials configured. This will cause any network requests to the PowerSync instance to fail.

The connecting step is only included in the Vite example to verify that all web worker config has been bundled correctly.

Great @stevensJourney, I imagined this. To stop the confusion, I'd add your hint to README and linking it to this issue.

I'm working on integrating auth with Stytch https://stytch.com/ (support React and React Native). Let's see if I finish it and open source the example. Your examples are little hard to follow because Supabase does everything.
