Error when using with vscode "TypeError: Cannot read property 'charAt' of undefined at in t in div in t in div in t in div in t ...."

Hi i get this error after some time when im using gophernotes with vscode. Maybe this is a vscode issues?

Have tried to figure when it works and when it breaks. Most of the time i can get things working again by restarting both vscode and gophernotes.
