I run some analysis, which outputs errors into quickfix list in neovim. I can then navigate to each error and all works fine. What I need next, is that error message contains some ID, which I need to access. So for example, I navigate to some error, and I can get idx from copen get(getqflist({‘idx’: 0}), ‘idx’, 0) which entry it is, but I do not know how to access that error message and take ID from it.
