TypeError: cancelInline is not a function

Problem

I believe the library tried to call a non-existant function.

Code snippet

import { env } from '$env/dynamic/private';
import { fail, type RequestEvent } from '@sveltejs/kit';
import { produce } from 'sveltekit-sse';

// ---------- not important in regards to the problem, just for context ----------
function delay(milliseconds: number) {
  return new Promise(function run(resolve) {
    setTimeout(resolve, milliseconds);
  });
}

async function getImg() {
  try {
    const url = env.IMAGE_URL;
    const response = await fetch(url as string);
    const json = await response.json();
    if (json.image) return json.image;
  } catch (err) {
    return null;
  }
}

async function testImgAcessibility() {
  const img = await getImg();
  if (img) return true;
  return false;
}

export async function POST(event: RequestEvent) {
  if (!event.locals.session) {
    return fail(400);
  }
  const imgAcessible = await testImgAcessibility();
  console.log('able to fetch image:', imgAcessible);
// ---------- ---------- the important part ---------- ----------
  return produce(
    async function start({ emit }) {
      console.log(
        'started streaming to:',
        event.locals.user!.type,
        '(session id: ' + event.locals.session!.id + ')'
      );
      while (true) {
        const img = await getImg();
        if (img) {
          const { error } = emit('message', img);
          if (error) {
            console.log('error in emit:', error);
            return;
          }
          await delay(16);
        } else {
          const { error } = emit('error', 'nullimg');
          if (error) {
            console.log('error in emit:', error);
            return;
          }
          await delay(1000);
        }
      }
    },
    {
      stop() {
        console.log('stopped streaming to:', event.locals.user!.type);
      }
    }
  );
}

Hello @KubaVejrazka , thanks for the issue!

I can't seem to reproduce it though but I think I figured what the problem was and fixed it.

Please update to version v0.13.11 and let me know if this fixed your issue.
