Websocket error on HTTP Operation

[yanover]

Hey guys !

I’m building a web interface to manage my LXD containers. I use the lxd-node library to make my requests.

I can get my hosts and containers, stop, start or restart them but when it comes to sending commands, it doesn’t work.

I know that the node-lxd project is no longer maintained and I hesitate to create my requests directly by querying the LXD API but I would still like your feedback :

This is my function to send a command, I took the same example as in the official documentation, I just retrieve my container with an external function (which is working) :

public async execute(
    host: HostDto,
    container: ContainerDto,
    command: CmdDto,
  ) {
    let target = await this.getContainer(host, container);

    target.exec(['sleep', '5'], (err, process) => {
      if (err != null) {
        console.error(err);
        return;
      }

      process.on('close', () => {
        console.log('process closed');
      });
    });
  }

Unfortunately, my server is saying :

Error: unexpected server response (400)
    at ClientRequest.response (D:\Programation\Nasticot\NAS-SERVER\project\node_modules\ws-unix\lib\WebSocket.js:704:15)
And this part of the Websocket library is the following :

if (!self.emit('unexpected-response', req, res)) {
    error = new Error('unexpected server response (' + res.statusCode + ')');
    req.abort();
    self.emit('error', error);
 }

I probably miss something … If anyone has an idea, it would be very appreciated !

Thank you
