Node.js v14 the hexo-util@ChachStream.getCache returns an empty array.

In Node.js v14 has many changes about stream. I think this issue caused by these changes.

Can you attach a sample code? Following code works for me in Node 14,

const { CacheStream } = require('hexo-util');
const { createReadStream } = require('fs')

const stream = new CacheStream();
createReadStream('testfile').pipe(stream)

stream.on('finish', () => {
  console.log(stream.getCache().toString());

  stream.destroy();
});

Last night, I added console.log(this._cache) in getCache method in my local env after that I confirmed this phenomenon when I exec hexo@generate.js test.

I think this issue caused by destroy method.
