Streaming does work not on Vite/MacOS

[Vlad Miller]

Reproduction

I have an absolutely fresh remix installation w/ streaming support.
https://github.com/vladmiller/remix-broken-streamin-test

The problem is that it does not work on my dev machine, however, the same code works in stakblitz.

I have tried downgrading local node to v18.20.2 (similar to what stackblitz) – example still fails.

Used Package Manager

pnpm

Expected Behavior

After two seconds, I expect to see This is your message: Hello world on the screen.

Actual Behavior

If fails with

This will always show.

Error loading message

Additional information

The code works on local environment in incognito mode, when all extensions are disabled.

Disabling all extensions and enabling them one by one reveals that it's Spoof Geolocation Extension that breaks the code.

Observation

This is not relevant to remix, and most likely an issue with the @hey-api/openapi-ts package, however, OpenAPI methods generated from @hey-api/openapi-ts are failing to defer.

return defer({
  clients: Oauth2Service.getApiV2Oauth2Clients()
})

Instead I need to wrap them in another promise

  return defer({
    clients: new Promise(async resolve => {
      resolve(await Oauth2Service.getApiV2Oauth2Clients())
    }),
  })

Can you clarify what you are expecting Remix to do here? The streaming repo you provided works fine for me locally in dev mode in both Chrome and Firefox. It seems like you've identified that this is an issue with the extension? Extensions have been known to cause React hydration issues in 18.2 so that may be of some help.

@brophdawg11 Reckon we can close the issue. I have opened the report before I have identified that it's the extension that causes troubles.
