Can you reproduce this without the jsx plugin? If so, can you give me a source file that triggers it?

[max-mykhailenko]

I can't now reproduce it, but it appears regularly. I'll send you a file when get this bug again.

I can reproduce with ST4, when typing a space at the end of the string or line(in script area of .vue file), it continuously popup the empty message.

~~And this might be the error log:~~

Traceback (most recent call last):
  File "/Applications/Sublime Text.app/Contents/MacOS/Lib/python33/sublime_plugin.py", line 893, in on_query_completions
    norm_res(callback(v, prefix, locations))
  File "/Applications/Sublime Text.app/Contents/MacOS/Lib/python33/sublime_plugin.py", line 129, in profiler
    return event_handler(*args)
  File "/Users/brownsugar/Library/Application Support/Sublime Text 3/Packages/tern_for_sublime/tern.py", line 68, in on_query_completions
    pathFirstCh = pathPrefix[0]
IndexError: string index out of range

I use Package Resource Viewer to debug, and I found the exception was came from https://github.com/ternjs/tern_for_sublime/blob/master/tern.py#L381

Can you find any .tern-port file in the project?

[brownsugar]

@othree No, there is no config file for Tern in the project.

[othree]

@brownsugar Can you provide a sample code and steps to reproduce(including configs you added). And AFAIK latest official release of Sublime Text is version 3. How do you use ST4?

[brownsugar]

@othree The only config I have is:

{
  "tern_argument_hints": true,
}

I think is not about the code, it happens randomly, I tested by same code in two files, one happened and the other not. You can download ST4 from ST official Discord server.

I believe it’s crashed or don’t have any request then it stopped itself. If it is crashed we have to find out why.
