How to use the ipfs-log.fromJSON function in ipfs-log

res.on('data', bufferData)
          res.on('end', done)
        })
      }

      const onProgress = (hash, entry, count, total) => {
        this._recalculateReplicationStatus(count, entry.clock.time)
        this._onLoadProgress(hash, entry)
      }

      // Fetch the entries
      // Timeout 1 sec to only load entries that are already fetched (in order to not get stuck at loading)
      const snapshotData = await loadSnapshotData()
      this._recalculateReplicationMax(snapshotData.values.reduce(maxClock, 0))
      if (snapshotData) {
        const log = await Log.fromJSON(this._ipfs, this.identity, snapshotData, { access: this.access, sortFn: this.options.sortFn, length: -1, timeout: 1000, onProgressCallback: onProgress })
        await this._oplog.join(log)
        await this._updateIndex()
        this.events.emit('replicated', this.address.toString())
      }
      this.events.emit('ready', this.address.toString(), this._oplog.heads)
    } else {
      throw new Error(`Snapshot for ${this.address} not found!`)
    }

    return this
  }
