container.attach writes attachOptions into container's stdin

[NoOneHardy]

When writing into container's stdin sometimes dockerode automatically writes attachOptions infront of the actual input.
Does anybody have the same issue and a possible solution?

Input

{"stream":true,"stdin":true,"stdout":true,"stderr":true,"hijack":true,"logs":false}say hello

Code

const container = docker.getContainer('720736bad7ecc2f1ced7364366a69e240d1a6ad5dea02f9a77f3c2b0bb7990ae')

container.attach({
  stream: true,
  stdin: true,
  stdout: true,
  stderr: true,
  hijack: true,
  logs: false
}, (_, stream) => {
  // Map output to console
  stream.pipe(process.stdout)

  const string = 'say hello\n'
  // Write data to the container's stdin
  stream.write(string)
})```
