How to start and change an IPLD structure

,
1

Hello, I try to write a new IPLD structure with js-ipfs (compiling code for in the browser) . First I make a new node with ipfs.object.new and the template ‘unixfs-dir’. Than I try to add something to the dag by using ipfs.object.patch.addLink
But it seems to get stuck in this patch step.
My code is:


          const cleannode = await ipfs.object.new({template: 'unixfs-dir'})     //(een leeg object.put wordt gezien als group en kan niet worden gebruikt daarom object.new)
          const hashcleannode = (cleannode.toString())
          const hashcleannodep = CID.parse(hashcleannode)
          log('hash of clean node: '+hashcleannode)
          log('hash of clean node after parse: '+hashcleannodep)
//logs:
//hash of clean node after parse: QmUNLLsPACCz1vLxQVkXqqLX5R1X345qqfHbsf67hvA3Nn

          const encoder = new TextEncoder()
          const decoder = new TextDecoder()
          const addOptions = {  pin: true }

          var { cid } = await ipfs.add(encoder.encode('hello ipld'), addOptions)
          for await (const chunk of ipfs.cat(cid)) {
            const addnode = (decoder.decode(chunk)) 
            const hashaddnode = (cid.toString())
            console.log ('what is in the node to be patched: '+addnode)
            console.log ('the hash: '+hashaddnode)
//logs:
//what is in the node to be patched: hello ipld
//the hash: Qmb6ECa7a72waFreKRxGk3S6dsm6XHaoWdTpKoxYqba24o

            const hey = {
              name: hashaddnode,
              size: 37,
              cid: CID.parse(hashaddnode)
            }
            const patchednode = await ipfs.object.patch.addLink(hashcleannodep, hey)
            const hashpatchednode = (patchednode.toString())
            console.log ('new patched node: '+hashpatchednode)
          }

//logs: 
//Uncaught (in promise) TypeError: Invalid DAG-PB form (extraneous properties on link object)

I hope anyone can help, :tophat:
