Error: Cannot import non-existent remote object
While attempting to import an existing object to
"azurerm_virtual_machine_data_disk_attachment.res-8", the provider detected
that no object exists with the given id. Only pre-existing objects can be
imported; check that the id is correct and that it is associated with the
provider's configured region or endpoint, or use "terraform apply" to create
a new remote object for this resource.

Hey @novohool, it looks like you tried to export a data disk attachment, which does not exist as a support resource in the azurerm provider. You could attempt to re-expor this using the AzAPI provider with option --provider-name=azapi and see if that works instead.
