Debug.lua

Error running Lua task: [71D78F4310179502] Utils:124: attempt to index a nil value (global 'debug')

look above, logcat output the error when I call :
local traceback = string.split(debug.traceback("", 2), "\n")

check the lua lib:

find debug.lua, I don't known what's wrong

There is no access to the lua internal debug.lua functions directly. I assume this is to do with how the scripts are used in Core, but that's just speculation on my part.

However, there is hope! In the editor, main menu, Window - Script - Script Debugger. Grab the tab and drop it somewhere useful (I usually put it next to the event log).

Check the first two debug buttons (pause on breakpoint and pause on error). So this is a start.

Next right lick on your script in the hierarchy and Edit Script (not Edit Script in External Editor). This opens a very basic looking text editor with your script in it - the only redeeming feature of this is that you can make single left clicks to the left of the line numbers to toggle breakpoints which work with the Script Debugger.

This is expected core only provide a subset of the lua implementation
Lua functions
The Sumneko extension refer to the whole lua api. So intellisense show definitions of functions not available in the lua version of core.
You can't access debug, io, most of os. Those libraries(tables) have been removed, some are partially removed e.g string.dump() or loadstring().

You can remove missing builtin lib with settings.json file e.g

{
    "Lua.diagnostics.globals": [
    ],
    "files.exclude": {
        "**/Scripts/*.pbt": true
    },
    "Lua.runtime.builtin": {
        "io": "disable",
        "debug": "disable"
    }
}

Don't forget to reload your window

This is only a partial fix because on some lib only some functions are missing.
Maybe a better fix involve disabling many libs and reintroduce the class and the definition in:

--- @class AIActivity : Object @AIActivity is an Object registered with an `AIActivityHandler`, representing one possible activity that the handler may execute each time it ticks.
--- @field name string @This activity's name.
--- @field owner AIActivityHandler @The AIActivityHandler that owns this activity. May be `nil` if this activity has been removed from its owner.
--- @field priority number @The current priority of this activity. Expected to be greater than 0, and expected to be adjusted by the `tick` function provided when adding the activity to its handler, though this can be set at any time.
--- @field isDebugModeEnabled boolean @True if this activity has debugging enabled in the AI Debugger. Useful for deciding whether to log additional information about specific activities.
--- @field isHighestPriority boolean @True if this activity is the activity with the highest priority among its owner's list of activities. Note that this value does not update immediately when setting an activity's priority, but will be updated by the handler each tick when the handler evaluates its list of activities.
--- @field elapsedTime number @If this activity is the highest priority for its handler, returns the length of time for which it has been highest priority. Otherwise returns the length of time since it was last highest priority, or since it was added to the handler.
--- @field type string
local AIActivityInstance = {}
--- @param typeName string
--- @return boolean
function AIActivityInstance:IsA(typeName) end

--- @class GlobalAIActivity : Object @AIActivity is an Object registered with an `AIActivityHandler`, representing one possible activity that the handler may execute each time it ticks.
AIActivity = {}

--- @class AIActivityHandler : CoreObject @AIActivityHandle is a CoreObject which can manage one or more `AIActivity`. Each tick, the handler calls a function on each of its registered activities to give them a chance to reevaluate their priorities. It then ticks the highest priority activity again, allowing it to perform additional work.
--- @field isSelectedInDebugger boolean @True if this activity handler is currently selected in the AI Debugger.
--- @field type string
local AIActivityHandlerInstance = {}

As @RedQuad said the only chance to debug is via the editor debugger.
But if you use debug to have some sort of reflection you have no luck
