transformPasted 's result ignored?

Yeah, I bet that’s the problem. I tried a few variations based on some answers below:

Best way to replace slice mutation

Creating a copy of a node with different marks is done with node.mark. Updating the content of a slice can be done by creating a new slice with an updated fragment.

Modify specific node on copy and paste (in clipboard)

Thought I will share some details of how I made it eventually. The general concept is that on copy we update attribute with external data and remove it on paste when it’s not needed. This approach may be helpful to support some similar workflows. First, I added new attrs to my custom Node called copyPasteData which expects a stringified object with external data structure. ... toDOM: (node: ProsemirrorNode): DOMOutputSpecArray => { return [ "span", { ..., "data-…

but still don’t am not getting this quite right:

          transformPasted(slice) {
            const content = slice.content.textBetween(1, slice.content.size);
            const nodes = slice.content.content.map((node, i) => i > 0 ? node : schema.nodes.heading.create({
	      ...node.attrs, copyPasteData: undefined
            }, node.content));

            const result = new Slice(
              Fragment.fromArray(nodes),
              slice.openStart,
              slice.openEnd
            )

            return result;
          }

Any thoughts on what might be going wrong?
