How to use layer cache when building images?

It looks like every time I build an image, it starts over.

My parameters:

const stream = await docker.buildImage(
{
  context: temporaryDirectory,
  src: ['Dockerfile', ...(files?.map((file) => file.name) ?? [])],
},
{
  abortSignal,
  platform,
  rm: false,
  t: tag,
  version: '1',
},
);

Turns out it was because of platform mismatch.
