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.

Parti dal callback on_query_completions e traccia il valore di current_file fino a TSC_IsTypeScript, usando le righe 48 e 50 indicate come punti di ingresso. Riproduci il problema in un buffer di Sublime Text senza titolo, quindi verifica che il completamento non produca alcun traceback al suo interno, mentre i file TypeScript salvati continuano a funzionare.
