Issue with go to definition

[ka1d013]

Hello,
i am quite new to nvim but i am having trouble using gd to for example for the definition of a function etc..., what happens is that it behaves like a * and highlights occurrences :

This is my lspconfig

local capabilities = require("plugins.configs.lspconfig").capabilities
local augroup = vim.api.nvim_create_augroup("LspFormatting",{})

local lspconfig = require("lspconfig")
local util = require "lspconfig/util"

lspconfig.gopls.setup {
  on_attach = function (client,bufnr)
   if client.supports_method("textDocument/formatting") then
      vim.api.nvim_clear_autocmds({
        group = augroup,
        buffer = bufnr,
      })
      vim.api.nvim_create_autocmd("BufWritePre", {
        group = augroup,
        buffer = bufnr,
        callback = function()
          vim.lsp.buf.format({ bufnr = bufnr })
        end,
      })
    end
  end,
  capabilities = capabilities,
  cmd = {"gopls"},
  filetypes = { "go", "gomod", "gowork", "gotmpl" },
  root_dir = util.root_pattern("go.work", "go.mod", ".git"),
  settings = {
    gopls = {
      completeUnimported = true,
      usePlaceholders = true,
      analyses = {
        unusedparams = true,
      },
    },
  },
}

Any ideas on how i can debug it further ? Thank you
