Question about Kafka: Parse correlation Id

Challenges
1

The solutions passes if we assume that the first two bytes of the header consists of api key.

connection.on('data',(data) => {
    const api_key = data.subarray(0, 2);
}

But, isn’t that the first 4 bytes in the header consists of size information? Why are we ignoring the size here?

2

the tester have not tests the header size here, acoording to the task description, it just validate the correlation id in this section.
