[1.14.4]readString() from server side

[Edivad99]

Good evening everyone, I have this class that reads a string through buf.readString(). I did a test to see if my mod had server-side problems and I had this error.

The class in question is at this link: https://github.com/Edivad99/DimStorage/blob/1.14.x/src/main/java/edivad/dimstorage/network/packet/UpdateBlock.java

I went to see the PacketBuffer::readString () method what it did and I saw that it is callable only on the client side.

How do I solve the problem?

But is it right how I set up the class?
