errors occur when right clicking the mouse

[fountainer]

When I right click the mouse, errors are printed in the console. When I disable this plugin, no error is printed. Windows 10. sublime text version: 3143. AligTab version: 2.1.8

Traceback (most recent call last):
  File "D:\software\Sublime Text 3\sublime_plugin.py", line 706, in is_enabled_
    raise ValueError("is_enabled must return a bool", self)
