Help with config Error executing vim.schedule lua callback

[fmorroni]

Hi, I have a custom config and have been trying to setup nvim-java. I'm using lazy as a package manager and I used the linked Kickstart repo as a guide to get this:

return {
  {
    "neovim/nvim-lspconfig",
    dependencies = {
      'williamboman/mason.nvim',
      'williamboman/mason-lspconfig.nvim',
      'nvim-java/nvim-java',
    }
  },
  {
    "williamboman/mason.nvim",
    opts = {},
    keys = {
      { "<leader>m", "<CMD>Mason<CR>", desc = "Open mason" }
    },
  },
  {
    "williamboman/mason-lspconfig.nvim",
    dependencies = { "williamboman/mason.nvim", 'saghen/blink.cmp', 'SmiteshP/nvim-navic' },
    config = function()
      require("mason-lspconfig").setup()
      require("mason-lspconfig").setup_handlers({
        -- Default handler
        function(server_name)
          require("lspconfig")[server_name].setup({
            capabilities = require('blink.cmp').get_lsp_capabilities(),
            on_attach = function(client, bufnr)
              if client.server_capabilities.documentSymbolProvider then
                require("nvim-navic").attach(client, bufnr)
                require("nvim-navbuddy").attach(client, bufnr)
              end
            end
          })
        end,
        jdtls = function()
          require('java').setup({
            jdk = {
              auto_install = false,
            },
          })
          require('lspconfig').jdtls.setup({
            settings = {
              java = {
                configuration = {
                  runtimes = {
                    {
                      name = "JavaSE-17",
                      path = "/usr/lib/jvm/java-17-openjdk/",
                    },
                    {
                      name = "JavaSE-21",
                      path = "/usr/lib/jvm/java-21-openjdk/",
                      default = true,
                    }
                  }
                }
              }
            }
          })
        end
      })
      require('user.plugins.lsp.keymaps')
    end,
  },
  {
    "folke/lazydev.nvim",
    ft = "lua", -- only load on lua files
    opts = {},
  },
}

It seems to be working fine (at least for the simple things I've tried), but I get an error every time I autocomplete from the LSP source.

Here's the error:

Error executing vim.schedule lua callback: /usr/share/nvim/runtime/lua/vim/lsp/rpc.lua:410: method "workspace/executeClientCommand": either a result or an error must be sent to the server in response
stack traceback:
	[builtin#36]: at 0x70e722bfe620

Given that the error shows up when autocompleting here's my completion config using blink (though it has nothing specific to java):

return {
  {
    'saghen/blink.cmp',
    -- dependencies = { 'rafamadriz/friendly-snippets' },

    -- use a release tag to download pre-built binaries

    dependencies = {

    },

        ['<C-e>'] = { 'hide' },
        ['<CR>'] = { 'select_and_accept', 'fallback' },
        ['<Tab>'] = { 'select_and_accept', 'fallback' },

        ['<Up>'] = { 'select_prev', 'fallback' },
        ['<Down>'] = { 'select_next', 'fallback' },

        ['<C-j>'] = { 'select_next', 'fallback_to_mappings' },

        ['<A-k>'] = { 'scroll_documentation_up', 'fallback' },
        ['<A-j>'] = { 'scroll_documentation_down', 'fallback' },

      },

      appearance = {
        nerd_font_variant = 'mono'
      },

      snippets = { preset = 'luasnip' },
      sources = {
        default = { "snippets", "lsp", "path", "buffer" },
        per_filetype = {
          sql = { 'snippets', 'dadbod', 'buffer' },
          lua = { "lazydev", "snippets", "lsp", "path", "buffer" },
        },
        providers = {
          lazydev = {
            name = "LazyDev",
            module = "lazydev.integrations.blink",
            -- make lazydev completions top priority (see `:h blink.cmp`)
            score_offset = 100,
          },
          dadbod = { name = "Dadbod", module = "vim_dadbod_completion.blink" },
        },
      },

      fuzzy = { implementation = "rust" },
      -- signature = {
      --   enabled = true,
      --   window = { show_documentation = false },
      -- },

      completion = {
        menu = {
          -- Don't automatically show the completion menu
          -- auto_show = false,

          -- nvim-cmp style menu
          draw = {
            columns = {
              { "label",      "label_description", gap = 1 },
              { "source_name" },
              { "kind_icon",  "kind",              gap = 1 }
            },
          }
        },
      }
    },
  }
}

Any ideas what might be the problem? Thanks!

Well it's even more broken than I thought. I doesn't seem to be properly building the workspace... When first opening the project the workspace build fine, but if I for example refactor a class and change its name then it doesn't get rebuilt, so other files still see it with the old name. Then after a while the old .class file gets removed but a new one with the new name doesn't get built. Even if I run JavaBuildBuildWorkspace the renamed class doesn't get rebuilt...
I also tried with this config which I had totally forgotten about, but the same thing happens.
