This problem occurs on a private cloud deployment.

[13349253469]

Public cloud deployment is not the problem

Sorry, but I need more information to help, ideally a self-contained example that shows same error

Currently only these error messages

Why is there undefined here?

[sidorares]

The only thing I can think of is that index is out of buffer boundary. Can you change your console.log to be
console.log("byte1",byte1, this.buffer.length, offset) ?

What is the cause of this situation?

I am more anxious now, I don’t know where to solve it.

Can you add packet.dump() before this line -

node-mysql2/lib/commands/query.js

Line 104 in 78aeaab

const rs = new Packets.ResultSetHeader(packet, connection);

So that I can copy packet data and reconstruct what happens on your side
