Demo page error: Uncaught DOMException: Document.querySelectorAll: '#esri-ocean/world_ocean_base' is not a valid selector

Thank you @ressa, for reporting this.
And yes there is a problem with the ERSI Ocean/World Ocean Base that code generate an html ID 'esri-ocean/world_ocean_base' which is not good.

You're welcome @berramou, thanks for a fast reply and update. I guess since you're not yet Maintainer on Gitlab, you can't make a branch and MR against 2.2-dev, since it doesn't exist yet ... as we discussed in #3449579-12: Add support for GDPR-friendly openstreetmap.de → .

Yes still don't have maintainer access.

Fixed in 2.2.2 →

Nice, thanks @berramou!
