Failed to execute 'send' on 'RTCDataChannel': RTCDataChannel send queue is full

[glitterlip]

What version of this package are you using?
9.11.1
What operating system, Node.js, and npm version?
node v16.15.0
npm 8.5.5
macOs 12.4
What happened?
I am using this package to send files.
When file size is small everything is ok.
But when I send a 240Mb file, after 28mb was received ,an Unhandled Rejection (OperationError): Failed to execute 'send' on 'RTCDataChannel': RTCDataChannel send queue is full error happened.
Then I change the code to

while (offset < filesize) {
      const chunk = await readChunk(offset)
      if (peer._channel.bufferedAmount >= peer._channel.bufferedAmountLowThreshold) {
        
        peer._channel.onBufferedAmountLow = () => {
          peer.send(chunk);
          peer._channel.onBufferedAmountLow = null;
        };
      } else {
        peer.send(chunk);

      }
    }

this time it just stuck forever after transfer >80Mb data.

while (offset < filesize) {
      const chunk = await readChunk(offset)
      if (peer._channel.bufferedAmount >= peer._channel.bufferedAmountLowThreshold) {
        await new Promise((resolve) => {
          setTimeout(() => {
            peer.send(chunk);
            resolve();
          }, 50);
        });
      } else {
        peer.send(chunk);
      }
    }

use promise and settimeout fix the problem ,but I have to wait and dont know 50ms is the proper duration
