@JasonGao180 Thanks for bug report!

I have 2 questions.

  1. Please tell me step1 & 2 of steps to reproduce below. That looks like "..."
  2. When did you use the installed package? I pushed latest version to github yesterday. then published to package registry just now. Sorry, I didn't increase the version number, because it was before the public.

Going to piggy back on this thread since i just had the same error and just installed it 5 minutes ago To replicate I did the following:

  1. Open a blank file
  2. Run mermaid previewer Errors with empty the empty file.

If instead you do:

  1. Open blank file
  2. Type in chart code
  3. Run Mermaid Previewer It produces no error. BUT if you continue to do:
  4. delete everything in the file Now it will produce the error again without having to rerun it.

Seems the error happens due to there being nothing to use for the previewer.

@vmuriart Thanks for report. I fixed it, and published the package latest version. Please again to try it.
