Description

I don't have many details for you sadly. I've seen this error 6 times in my Sentry logs, 3 times in the past month. All I really have for you is the info below. I hope it helps, please let me know if there's anything more I can provide.

Steps to check or reproduce

Running:

    "@egjs/flicking-plugins": "4.6.0",
    "@egjs/vue-flicking": "4.10.4",

Hello @taidaid! It's an easy fix by filtering the slots, but I can't tell if the problem is in getRenderingPanels or _getSlots. So, I'm guessing that fix would stop the error, but the rendered element would likely not be the desired result. I would like to know if you could give me some more information to reproduce the issue, such as the rendering function you're using.

Hello @WoodNeck , thanks for the quick response.

I'm not sure where I can get the exact info you need. Hopefully this helps

      <VueFlicking
        ref="vueFlickingEl"
        :options="{
          moveType: 'snap',

I tried to reproduce this issue but I couldn't. I think getRenderingPanels is giving the wrong values, which might be the cause of this issue and #783, but I can work on it once after reproducing the issue. If you find a way to reproduce the issue, could you please let me know?

Ok @WoodNeck , thanks for the quick investigation. I have only 2 reports of this issue after using your library for over a year, so I would classify it as a very low-occurrence bug. Thanks for all the hard work! :grin: If I learn more about it, I'll be sure to update this.

@taidaid Thank you! We'd really appreciate it if you could :)

Hello again, I'm guessing this is related to the same bug, so here's my Sentry info on a new occurrence:

TypeError Array.map(<anonymous>) 
Cannot read properties of undefined (reading 'toggle')
