LSP attached to buffer but no Sonar warnings (4.3.1.77786)

Version of Sonar server I am using is 4.3.1.77786

I have configured Sonar and used absolute paths to eliminate any issues related to the $MASON environment variable. I am not using a Node.js version manager (such as nvm or fnm); Node.js v22 is installed system-wide. Despite this, no information is being displayed.

This is my sonar config:

local filetypes = { "dockerfile", "java", "python", "php", "javascript", "typescript", "vue" }

return {
  {
    "https://gitlab.com/schrieveslaach/sonarlint.nvim",
    ft = filetypes,
    config = function()
      local capabilities = require("cmp_nvim_lsp").default_capabilities()
      require("sonarlint").setup {
        server = {
          cmd = {
            "/home/hassan/.local/share/nvim/mason/packages/sonarlint-language-server/sonarlint-language-server",
            "-stdio",
            "-analyzers",
            "/home/hassan/.local/share/nvim/mason/share/sonarlint-analyzers/csharpenterprise.jar",
            "/home/hassan/.local/share/nvim/mason/share/sonarlint-analyzers/sonarcsharp.jar",

            "/home/hassan/.local/share/nvim/mason/share/sonarlint-analyzers/sonarjavasymbolicexecution.jar",
            "/home/hassan/.local/share/nvim/mason/share/sonarlint-analyzers/sonarjs.jar",
            "/home/hassan/.local/share/nvim/mason/share/sonarlint-analyzers/sonarlintomnisharp.jar",
            "/home/hassan/.local/share/nvim/mason/share/sonarlint-analyzers/sonarphp.jar",

          },
          capabilities = capabilities,
        },

        filetypes = filetypes,
      }
    end,
  },
}

This is my ftplugin/java.lua config:
