0x0 0x0 Error- How to Fix it?

The error occurs as a result of user error. It happens when users don’t return from the HTTP handler. After generating their desired output, it is essential to return to flush and terminate the connection.

When users don’t loop the HTTP handler, they set up a never-ending cycle that eventually overflows the stack and results in an error. 

Additionally, the built-in print function often leads to this result. This is because they’re tough to use. Thus, it is best to avoid them. Users can opt for the fmt print functions as they’re easier to use and offer more features.
