From one day to the next, I’ve suddenly been having issues using the VSCode Extension.
Oddly enough it’s only for loading Scripts.. All other functionality seems to function perfectly fine.
We had the issue recently as well, with PSU 5.3.3 and VSC extension 5.5.0 and 5.5.1. It seems that the current versions of the VSC extension are not backward compatible. Upgrading our PSU server to 5.5.2 resolved the issue and the VSC extension connects again without any further modifications.
