Succeed when replacing :
await kb.updater.updateMany(ds)
by :
for (let i in ds) await kb.updater.update(ds[i])

kb.updater.updateMany is a clone of https://github.com/solid/contacts-pane/blob/1813eac3b885c3d86fa4ed2882fb73d4ec0fabcf/contactLogic.js#L13

export async function updateMany (deletions, insertions) {
  const docs = deletions.concat(insertions).map(st => st.why)
  const uniqueDocs = Array.from(new Set(docs))
  const updates = uniqueDocs.map(doc =>
    kb.updater.update(deletions.filter(st => st.why.sameTerm(doc)),
      insertions.filter(st => st.why.sameTerm(doc))))
  return Promise.all(updates)
}

const uniqueDocs = Array.from(new Set(docs)) is incorrect because all objects are different, we must compare the content.
We can use rdflib.js sameTerm or equals that make a node key value comparison in something like :

const uniqueDocs = []
docs.map(doc => {
    if (!uniqueDocs.find(item => item.sameTerm(doc))) uniqueDocs.push(doc)
 })
