LSP info not showing

[Uri Arev]

I tried TJ's statusline config and the LSP part (current function, errors etc.) isn't working

[Uri Arev]

@tjdevries Any help? I saw you using it in a stream

[TJ DeVries]

paste EXACTLY the config you have.

This is my config, from your config_manager.

I have same issue with this config (I just change ws_diag function nothing changed everything is same as your config)
it work if a send buffer manually but not working in statusline

local ws_diagnostic_counts = function(_, buffer)
    if not has_lsp_extensions then
        return ""
    end

    local messages = {}

    local error_count = ws_diagnostics.get_count(buffer.bufnr, "Error")
    local hint_count = ws_diagnostics.get_count(buffer.bufnr, "Hint")
    local warnings_count = ws_diagnostics.get_count(buffer.bufnr, "Warning")
    local info_count = ws_diagnostics.get_count(buffer.bufnr, "Information")

    table.insert(messages, 'E ' .. error_count )
    table.insert(messages, 'W ' .. warnings_count )
    table.insert(messages, 'H ' .. hint_count)
    table.insert(messages, 'I ' .. info_count )

    return table.concat(messages, " ")
end

    local items = {
      { mode, required = true },
      { git_branch },
      { " " },
      { sections.split, required = true },
      { git_icon },
      { sections.maximum_width(builtin.responsive_file(140, 90), 0.40), required = true },
      { sections.collapse_builtin { { " " }, { builtin.modified_flag } } },
      { sections.split, required = true },
      { show_current_func },
      { lsp_statusline.server_progress },
      { ws_diagnostic_counts },
      { git_changes },
      { "[" },
      { builtin.line_with_width(3) },
      { ":" },
      { builtin.column_with_width(2) },
      { "]" },
      {
        sections.collapse_builtin {
          "[",
          builtin.help_list,
          builtin.readonly_list,
          "]",
        },
      },
      { builtin.filetype },
    }

Can use new diagnostic module for nvim 0.6, It works better and has actual APIs. See :help el.diagnostic
