API 4.33 error, basemapGallery.destroy() generates error.

In my code I dynamically add a basemapGallery:

basemapGallery = document.createElement('arcgis-basemap-gallery'); basemapGallery.position = "bottom-right"; mapDiv.appendChild(basemapGallery);

I remove the basemapGallery by pressing a button:

if (basemapGallery.destroy && typeof basemapGallery.destroy === 'function') { basemapGallery.destroy(); } basemapGallery = null;

Using API 4.32 this works when I use the imports:

But when I use the API 4.33 imports, I get an error on basemapGallery.destroy():

The error is:

Uncaught (in promise) TypeError: can't access property "state", this.source is undefined

When I change the last import line to version 4.32 it works without the error

Is there something I overlooked or is this an API error?

Hi @Wimvan_Dijk - this is an API error. We have a fix that will be released with version 4.34 next month.
If you want to test out the fix ahead of the release, you can do so on our development version of the CDN:

https://js.arcgis.com/next

https://js.arcgis.com/next/map-components/

Note that as of 4.33, there is a new CDN endpoint for components where the version number comes before the component package for consistency with the core API CDN! See https://developers.arcgis.com/javascript/latest/release-notes/#new-cdn-endpoint-for-components for more info.
