An error occurs in the process of receiving data through sslstream and decoding BR.
Here's the full source. If you do it In the sentence below, the first data is converted normally, but an error occurs in the second data. Why is that so?
>> byte[] bbb = Brotli.DecompressBytes(body); // an error occurs in the second data
