My Lua plugin, which doesn't do anything fancy, breaks nlua.nvim's diagnostics

[f-person]

When I enable git-blame.nvim, diagnostic messages don't show up in Lua files/projects. When I open a Lua file that is not in a Git repo, diagnostics work. After disabling git-blame.nvim, diagnostics also work. I have no idea why this would happen. git-blame.nvim and sumneko_lua work fine together.

Here's how I set up nlua:

require'nlua.lsp.nvim'.setup(lsp, {
    on_attach = on_attach,
    globals = {'love'},
    disabled_diagnostics = {'lowercase-global'}
})

And default sumneko_lua:

lsp.sumneko_lua.setup {on_attach = on_attach}

My on_attach:

local on_attach = function(_, bufnr)
    require'completion'.on_attach({
        sorter = 'none',
        matcher = {'substring', 'exact', 'fuzzy'}
    })

                                '<cmd>lua vim.lsp.diagnostic.show_line_diagnostics()<CR>',

                                keymap_opts)
    vim.api.nvim_buf_set_keymap(bufnr, 'n', '<leader>cd',
                                '<cmd>lua vim.lsp.diagnostic.set_loclist()<CR>',
                                keymap_opts)
end

I initialize the lsp variable at the top of init.lua:

local lsp = require('lspconfig')

Maybe you have some ideas about why this would happen?

Here's my full init.lua: https://github.com/f-person/dotfiles/blob/6528831614/.config/nvim/init.lua

The problem disappeared after installing the language server with the provided script or some other changes were done (either in nlua.nvim or in git-blame.nvim). Anyways, plugins coexist in peace now.
