Describe the bug
Im trying a simple prompt to open google and search dog but having error on the start.

MCP error -32602: Invalid arguments for tool mobile_list_available_devices: [ { "code": "invalid_type", "expected": "object", "received": "undefined", "path": [], "message": "Required" } ] (Code -32602)

then i checked the other tools to check if it's only mobile_list_available_devices that was failing for me. However, it seems that out of the 15 tools, 6 have failed, all of which outputs the same error stated above.

• mobile_list_available_devices
• mobile_get_screen_size
• mobile_take_screenshot
• mobile_list_apps
• mobile_get_orientation
• mobile_list_elements_on_screen

my current config:

"mcpServers": {
    "mobile-mcp": {
      "command": "D:\\nvm4w\\nodejs\\node.exe",
      "args": [
        "D:\\npm-global\\node_modules\\@mobilenext\\mobile-mcp\\lib\\index.js"
      ],
      "env": {
        "ANDROID_HOME": "D:\\Me\\Android\\Sdk"
      }
    }
  }
