Error while running event Todo-List-Continued::on_gui_click (ID 1)
Todo-List-Continued/todo/features/export_task.lua:6: attempt to index global 'global' (a nil value)
stack traceback:

Just chiming in to say i got the exact same error, it happend when clicking on the quick acces button top left of the screen.
It also seems to happen when trying to open in a different matter and after creating a new task.
It was working fine before so no sure what changed, i had about 2 task marked as completed, about 3 still left open in the list.
I had about 9 other mods loaded, in case that seems related hit me up.
The mod version is 20.0.2
Hope this helps, good luck

Having this error as well, when I hit the "Toggle Todo List" button on the quick access bar. Here is a save that should allow you to replicate the issue: https://mega.nz/file/1GdWwKSR#t9SWtrz-NJ1B4yMO2KCUI_LFtQOpYEx7vYweohpoXW0
Just load the save file (sync mods, probably related to a mod interaction) and just hit the button on the GUI and that should reproduce the crash.

Came to say I'm having the same issue, mod is unusable for me in current state. Great mod tho, I miss it very much

Slightly different error, probably same cause though:

To mattias1172, for a solution to this...

In the 2.0 version of Factorio, the 'global' object was replaced with (or renamed to) 'storage'. In the code, just do a Find & Replace on this, and you should be good. I was able to make the changes locally and get the mod working.

Reach out if you have any questions.

Cegreer is right. Idk if it's possible to throw here a modified version of .zip? I didn't find a way to do this (otherwise i could upload mine .zip). But you can
- open .zip (C:\Users\<username>\AppData\Roaming\Factorio\mods.
- extract it somewhere
- open folder with editor which will allow you to replace multiple instances of text.
- replace global with storage everywhere (changelog can stay like it is)
- pack folder back into .zip
- replace original .zip with one you have created.

At least it works for me.
Thanks cegreer :)

P.S. I assume global is some kind of reference to predefined ingame variable or something like this
