Fix

The panic "invalid memory address or nil pointer dereference" occurs because your code attempts to access a field or method on a pointer that is nil.

// Example: Accessing a nil pointer causes the panic
var ptr *MyStruct
ptr.Value = 10 // panic: invalid memory address or nil pointer dereference

// Fix: Initialize the pointer before use
ptr = &MyStruct{}
ptr.Value = 10

To fix this, ensure the pointer is initialized (e.g., &MyStruct{}) or check if it is nil before dereferencing it.

The "invalid memory address or nil pointer dereference" error in Go means your program tried to use a variable that hasn't been created yet or is empty. Imagine trying to open a door that doesn't exist; the program crashes because it can't find the memory it needs. You must create the object or check if it exists before trying to use it.
