Failed to execute 'observe' on 'ResizeObserver': parameter 1 is not of type 'Element'

[ghoshsanjoy78]

I am using Meteor with svelte and svelte-grid. Created a basic svelte app in Meteor using

meteor create --svelte svelte-app

Then added the svelte-grid package and trying out the basic examples provided on the svelte-grid app as is. The examples don't run and I see this error in the console:

Uncaught TypeError: Failed to execute 'observe' on 'ResizeObserver': parameter 1 is not of type 'Element'.

Any thoughts on how to fix this. The issue occurs only when running with Meteor.

I'm having the same issue trying to develop an Obsidian plugin. In my case the container isn't defined and that's why the ResizeObserver is failing..

I was able to get around this by importing from source.

    import Grid from "svelte-grid/src/index.svelte";
    import gridHelp from "svelte-grid/src/utils/helper";

hi all! I have the same error, in my case I use the webpack configuration for the project and not rollup, everything works fine in rollup, not in webpack, I tried this option:

import Grid from "svelte-grid/src/index.svelte";
import gridHelp from "svelte-grid/src/utils/helper";

did not help, still the same error, I also want to note that only a part of the svelte-grid files, such as index.svelte and MoveResize/index.svelte, do not build/do not load in the run-dev mode at all, hence the errors , any ideas? @JacobSieberg @jplattel
