Bad Content-Length when use octokit upload asset with webStream

[Gaubee]

This code works fine

octokit.repos
      .uploadReleaseAsset({
        headers: {
          "Content-Type": mime.getType(path.extname(filepath)) || "application/octet-stream",
          "Content-Length": totalSize.toString(),
        },
        ...baseParams,
        release_id: release_id,
        name: path.basename(filepath),
        data: fs.readFileSync(filepath) as any,
      })

but not this one

octokit.repos
      .uploadReleaseAsset({
        headers: {
          "Content-Type": mime.getType(path.extname(filepath)) || "application/octet-stream",
          "Content-Length": totalSize.toString(),
        },
        ...baseParams,
        release_id: release_id,
        name: path.basename(filepath),
        data: stream.Readable.toWeb(fs.createReadStream(filepath)) as any,
      })

got error:400 HttpError: Bad Content-Length
