Describe the bug / error

this page

specifies the scheme for content type bindings.
however, when I use the sample provided and upload a package to SharePoint online (o365) I get the error

There were problems with the app web definition in the package.Details: Deployment failed in host web https://hideandseekdigital.sharepoint.com/sites/AFP-Integration for app AFP Intranet App Customiser/1bd5c67d-11c2-4372-8c72-9569b23ecb5e.

Steps to reproduce

1. create a SPFX project (in my case an extension)
2. add xml asset to bind a content type to a list. make sure the ContentTypeId is a valid one and the list exists in the specified listurl
3. package and upload to site, try to add app to site

Expected behavior

Either

1. the documentation is wrong and does not apply to sharepoint online anymore - in which case update it!
2. there is a bug that sharepoint online does not recognise the schema it should

Hello @ishaisagi-hns,
Thank you for bringing this issue to our attention. We will look into it and get back to you shortly.

@ishaisagi-hns,
We could not encountered error like above, can you please confirm which extension are you using?

[ishaisagi-hns]

By extension I mean the type of project (app customiser = extension).
So create an app customiser project and add the xml as per documentation.
