Markdown-preview-enhanced: Uncaught TypeError: this.webview.getWebContents is not a function

Created on 6 Apr 2021 · 6Comments · Source: shd101wyy/markdown-preview-enhanced

[Enter steps to reproduce:]

Open a markdown file by selecting it from the tree view
Markdown Preview panel opens and renders, but also throws the same exception twice

Basically everything seems to work except that it is throwing this exception which is popping up each time. It's the getWebContents method on webview, apparently it was deprecated way back and then removed entirely in Electron 8.0. Relevant info: https://github.com/electron/electron/blob/40d779a7f331291304d7f06312be0491c0429643/docs/breaking-changes.md#removed-webviewgetwebcontents

Unfortunately I have not tried this in safe mode myself.
