AttributeError: 'NoneType' object has no attribute 'endswith'

Getting this traceback:

Traceback (most recent call last):

  File "/Applications/Sublime Text.app/Contents/MacOS/sublime_plugin.py", line 377, in on_query_completions

res = callback.on_query_completions(v, prefix, locations)

  File "TSCompletion in /Users/rc/Library/Application Support/Sublime Text 3/Installed Packages/TypescriptCompletion.sublime-package", line 50, in on_query_completions

  File "TSCompletion in /Users/rc/Library/Application Support/Sublime Text 3/Installed Packages/TypescriptCompletion.sublime-package", line 258, in TSC_IsTypeScript
AttributeError: 'NoneType' object has no attribute 'ends with'

On line 48, is this statement:

current_file = view.file_name()

file_name() returns None and the call to the TSC_IsTypeScript(current_file) (line 50) tries to see if the filename ends with ".ts". I have an untitled file that I'm working on, so I suppose None is a valid state for the file_name to be in. As soon as I save it, it no longer has this error, this definitely an edge case.

Beginnen Sie beim on_query_completions-Callback und verfolgen Sie den Wert von current_file in TSC_IsTypeScript, wobei die gemeldeten Zeilen 48 und 50 als Einstiegspunkte dienen. Reproduzieren Sie das Problem in einem unbenannten Sublime Text-Puffer und überprüfen Sie anschließend, dass die Vervollständigung dort keinen Traceback erzeugt, während gespeicherte TypeScript-Dateien weiterhin funktionieren.
