Could you share a minimal script to reproduce this issue?

I have got the same error while trying to use markdownreveal 0.3.5 with Python 3.8.3, which seems to be the same case as @mamueFM. Steps to reproduce:

pip install markdownreveal==0.3.5
echo -e "# Test\n\nThis is a test" > test.md
markdownreveal test.md

I am not sure this is a problem with python-livereload; I believe that markdownreveal should call Server.serve instead of Server.application.

@ziotom78 I just updated Markdownreveal. Try to install the latest release (0.3.6) and see if it works for you.

The fix consisted on simply downgrading livereload to 2.6.2. If you want to contribute a fix to make it compatible with the latest livereload release, you are more than welcome: markdownreveal/markdownreveal#53 😊
