I get the following error when compiling

  Arduino IoT Cloud Variables description

  The following variables are automatically generated and updated when changes are made to the Thing

  String wifi;
  int speed;
  bool led;
  bool mode;
  bool power;

  Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
  which are called when their values are changed from the Dashboard.
  These functions are generated with the Thing and added at the end of this sketch.

This is not a valid line of code, as the comment suggests. Replace it with one or more valid lines of code that do something useful.

Your topic does not indicate an issue with IDE 2.x and hence has been moved to a more suitable location on the forum.

In future, please mention the board that you are compiling for.
