QUIC STREAM EVENT RECEIVE Buffer Size not as I expected

[chemsallioua]

Hi,
I am trying to make a Server and Client to stream data in real-time, and I am sending data buffers with size 2072 bytes over 6 STREAMS.
This is the logs I am getting when I print out the buffer size when the steam callback is called.

[2024-06-20 14:24:58] DEBUG: [ClientStreamCallback][strm][0x7f0500016fb0] Data received: Stream ID: 0 BuffSize: 2072

As you can see, Stream ID: 5 BuffSize: 1176 is not as expected, and it is actually lower than the 2072 byte I expect. does this represent a part of the data I sent? Why this happens and when do I expect to receive the rest of the data?

Thank you!
