Archive data is corrupt when not truncated

[mojavelinux]

The archive data becomes corrupt if the server doesn't truncate it. That's because the getArchiveJson function is returning a JSON object in one case (when truncated) and a string otherwise. In the case it returns a string, it gets spread into another JSON object, which leads to corrupt data.

The function should look like this:

function getArchiveJson (archive) {
  if (archive.truncated) {
    return fetch(archive.raw_url).then(resp => resp.json())
  }
  return JSON.parse(archive.content)
}
