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

See original GitHub issue

Recently got two error messages on sentry. Both are from an Android 4.4.4 device on a Chrome browser (Chrome 73.0.3683)

Not sure if I can help in any way or if they are related (let me know if it’s better to create a separate issue for the second one). 1)

I had the same issue, but the issue happened lazy loading a component having a v-if.

In my case I had the error on route leave, because in the beforeRouteLeave I was cleaning the object, making the v-if false, so on LazyHydrate self cleaning the object was not present. Easily fixed by wrapping my component in a div.

Maybe this solution can be helpful for somebody else!

I had the same issue when I used with <component :is="someComponent" />

Example:

<LazyHydrate v-slot="{ hydrated }" on-interaction>
  <component :is="someComponent" v-if="hydrated" />
</LazyHydrate>
