[Python] LLDB running a Python debugging script. I'm getting error: invalid thread

I'm trying to run a Python debug script in LLDB, but I'm getting invalid thread errors. I'm not sure why.

Here are my programs:

main.c:

#include <stdio.h>
#include <stdlib.h>

int addNumbs(int a, int b)
{
return a+b;
}

int main()
{
int a =5;
int b= 24;

int total = addNumbs(a,b);

printf("%d\n", total);

return 0;
}


My python debugging script debugersample.py:

import lldb

debugger = lldb.debugger

debugger.HandleCommand("b main")
debugger.HandleCommand("r")

for i in range(0,3): #execute next 3 times
debugger.HandleCommand("n")

debugger.HandleCommand("bt")


Running LLDB:

clang -g main -o main
lldb ./main
(lldb) command script import debugsample.py

Breakpoint 1: where = main`main + 15 at main.c:11:9, address = 0x0000000100003f0f
Process 5344 launched: '/Users/xxxx/CLionProjects/C_Practice/main' (x86_64)

10 {
-> 11 int a =5;
12 int b= 24;

14 int* ptr = (int*)malloc(sizeof(int));
Target 0: (main) stopped.


Note: When I run these commands in LLDB Python's interactive interpreter line by line, it works fine.
