I'm working on clipping a basemap in ArcGIS Pro (3.1.1) and sharing as a Web Layer for use in ArcGIS Online using these instructions: https://support.esri.com/en-us/knowledge-base/how-to-clip-basemaps-to-display-a-specific-area-in-arc...
However, when I try to share it with my ArcGIS Online account, I'm prompted with the following error and the clipped basemap does not upload properly.
That workflow does not apply to Esri basemaps, they cannot be republished like you try to do here. You would need to create your own basemap using your own data for this workflow to work.
Maybe I'm misreading this article, but it appears to be possible: https://support.esri.com/en-us/knowledge-base/how-to-clip-basemaps-to-display-a-specific-area-in-arc...
Or at least gives that impression.
If you open the help documentation related to the warning in your screenshot you can read that Service Layers are unsupported:
But I agree, this is not clear from the support article you have referenced.
Thank you, appreciate the clarification!
I wonder if you can create your own Vector Tile Style Basemap using the ArcGIS Vector Tile Style Editor and then deploy that to your portal. There's a great ArcGIS StoryMap about this here - Basemap Basics (arcgis.com)
