How to use the ipfs/src/http/gateway/utils/path.joinURLParts function in ipfs

const dirCid = err.cid
      console.log('resolver.directory', dirCid.toBaseEncodedString())
      const data = await resolver.directory(ipfs, url, dirCid)
      console.log('resolver.directory', Array.isArray(data) ? data : `returned '${typeof data}'`)
      // TODO: redirect so directory always end with `/`
      if (typeof data === 'string') {
        // return HTML with directory listing
        return {
          content: textBuffer(data),
          contentType: 'text/html',
          contentEncoding: 'utf-8'
        }
      } else if (Array.isArray(data)) {
        console.log('resolver.directory.indexes', data)
        // return first index file
        path = PathUtils.joinURLParts(path, data[0].name)
        return getResponse(ipfs, url, path)
      }
      throw new Error('Invalid output of resolver.directory')
    } else if (err.parentDagNode && err.missingLinkName) {
      // It may be legitimate error, but it could also be a part of hamt-sharded-directory
      // (example: ipns://tr.wikipedia-on-ipfs.org/wiki/Anasayfa.html)
      // which is not supported by resolver.cid from ipfs-http-response at this time.
      // Until ipfs.resolve support with sharding is added upstream, we use fallback below.
      // TODO remove this after ipfs-http-response switch to ipfs.resolve
      // or sharding is supported by some other means
      try {
        const matchingLink = (await ipfs.ls(err.parentDagNode, { resolveType: false })).find(item => item.name === err.missingLinkName)
