Crash opening manager

[jengo]

Describe the Bug

I recently upgraded to 0.4.14 and I am now getting an error that is slightly random but very frequent. This exception causes the game to exist.

To Reproduce

Steps to reproduce the behavior:

I have bound the manager to ctrl+t, using those keystrokes usually triggers the error

The mod LTN Manager (0.4.14) caused a non-recoverable error.
Please report this error to the mod author.

Error while running event LtnManager::ltnm-toggle-gui (ID 195)
__LtnManager__/scripts/util.lua:62: attempt to call field 'is_valid_sprite_path' (a nil value)

Save file & Username

Save file is large, it's a 1,100 hour game with 1,609 stations lol https://www.icloud.com/iclouddrive/03dWnyfZK09FdSs6Z6NRxbjxg#2021-11-04_py_save-n

Log file

Attach factorio-current.log, found in Factorio's user data directory.

I can also repeat this.

Problem is the call gui.is_valid_sprite_path(sprite), where is_valid_sprite_path is undefined in flib version 0.10.1. LTN Manager works again if I change the line into

if gui.is_valid_sprite_path and gui.is_valid_sprite_path(sprite) then

Although I am not sure things work as intended.

is_valid_sprite_path is a Factorio API function not flib so just change the gui to game and it works.

if game.is_valid_sprite_path(sprite) then

Same here:

This problem has been solved here. Is not it so?
