Current behavior 😯

Once in a while dev server crashes with an error:

TypeError: Cannot read properties of null (reading 'createServerReference')

After making some changes and hot reload it disappears.

Expected behavior 🤔

No response

Steps to reproduce 🕹

Steps:

1. Create init project
2. Add server cache in Home:

const getHello = cache(() => {
  "use server";
  return { message: 'hello; };
}, "hello");

export const route = {
  load: () => getHello(),
};

export default function Home() {
  const hello = createAsync(getHello);
  // ...

3. Do some changes in Home component
4. Sometimes it crashes, sometimes it resumes. Hard to recreate exact steps, it seems random (I suspect some kind of race condition).

It crashes for server functions. if you remove the load function, first load doesn't get any errors but if you navigate back, it gets the null error. The error shows in local production build and dev

  "dependencies": {
    "@solidjs/meta": "^0.29.2",
    "@solidjs/router": "^0.11.5",
    "@solidjs/start": "^0.5.3",

    "vinxi": "^0.2.1"
  },

I am having no luck reproducing this. I know it is supposed to be hard to reproduce, but I understand the original issue is related to dev environment. I'm just not seeing this no matter what I do.

@senabi are you saying you see this message a different way. Most specifically around createServerReference? Cannot read properties of null in general can happen for a variety of reasons but I'm interested around createServerReference.

@ryansolid sorry for the late response. The exact error I got is Cannot read properties of null (reading 'startsWith') using. the basic template. But it seems it's been partially solved by #1328 .

I think this was fixed, I also had this. This was fixed by #1329. It's been out since 0.5.6

Seems like this is fixed. if it's still an issue, reopen this issue. Try with latest solid-start and vinxi.
