When using Helia to send a large file, the connection was disconnected

[fastalks]

Step1

create unixfs to addfile on Node1 , then send CID to Node2.

helia = await createHelia(
    {
      libp2p,
      blockBrokers:[bitswap()]
    }
  )
const ufs = unixfs(helia)
const fileCID = await ufs.addFile({
    path:filePath,
    content: fileStream,
    mode: 0x755,
    mtime: {
      secs: BigInt(new Date().getMilliseconds()),
      nsecs: 0
    }
  });

Step2

cat File on Node2

 try{
    const ufs = unixfs(helia)
    const cid = CID.parse(cidString)
    const writeStream = fs.createWriteStream(outputPath);
    let receiveBytes = 0;
    for await (const chunk of ufs.cat(cid,{
      signal:AbortSignal.timeout(100 * 1000),
      onProgress:(evt)=>{
        const { bytesRead, totalBytes, fileSize } = evt.detail
        const bytesReadNumber = Number(bytesRead)
        const totalBytesNumber = Number(totalBytes)
        if (bytesReadNumber && totalBytesNumber) {
          const progress = bytesReadNumber / totalBytesNumber
          const fileId = cidString
          libp2pNode?.services.pubsub.publish('progress-notice',uint8ArrayFromString(JSON.stringify({fileId,progress})))
        }
        
      }
    })) {
      writeStream.write(chunk);
    }
    writeStream.end();
    console.log('File transfer complete');
  } catch(err) {
    console.log(err)
  }

The connection disconnects every time after transferring a few MB, with no errors

Any help would be greatly appreciated
