VS Code integration not working

How did you install golangci-lint?

Official binary

Description of the problem

golanci-lint version: 2.0.0
VS Code version version: 1.98.2
VS Code Go extension version: 0.46.1

The VS Code integration suggested here doesn't seem to be working for the linters as I can't see any problems raised, however, when I run golangci-lint run --fast-only from the terminal there are errors being flagged. See details on the verbose output section.

Worth mentioning that the same settings work for the formatter as expected.

Hey, thank you for opening your first Issue ! 🙂 If you would like to contribute we have a guide for contributors.

Hello,

The configuration suggested by the doc works as expected: the flag --fast-only is not the equivalent of the previous flag --fast.

This is explained here: https://golangci-lint.run/product/migration-guide/#lintersfast

I get that, but in my config file I am enabling cyclop which is a fast linter and still getting no problems raised in VS Code.

There was a similar issue raised on vscode-go repo - here.
