Newb can't navigate to next error

[danbills]

Hello, I'm trying to navigate to errors using :cnext and :lnext to no avail.

:cnext shows E42: No errors and :lnext says E776: No location list.

I'm sure I'm missing something basic, but I think I'm at the end of my vim-fu and am stuck.

The language server client in neovim reports diagnostics via the vim.diagnostic module. See :help vim.diagnostic.

You can move to the next/previous using either :lua vim.diagnostic.goto_next() or :lua vim.diagnostic.goto_prev()
