Unable to make it working

I’m unable to get errors in editors, I’ve try with different versions of Typescript, Eslint, @typescpt-eslint/parser (either older or newer versions). It doesn’t work also in Visual Studio.

I don’t know how to diagnose this issue, I have no clue where to look at. In the tsserver.log seems that the plugin was load correctly but no error show up in the editor:

Info 27   [8:14:23.524] Enabling plugin typescript-eslint-language-service from candidate paths: c:/Users/leoniDAM/Dev/Projects/Pretty/tsplugin/node_modules/typescript/lib/tsserver.js/../../..

Info 91   [8:14:28.515] [typescript-eslint-language-service] use '@typescript-eslint/parser'

this with:

eslint: 6.0.1
@typescript-eslint/parser:  2.0.0
@typescript-eslint/eslint-plugin: 2.0.0
typescript-eslint-language-service: 1.4.0

Instead with the latest versions of the packages in the tsserver.log I have:
