This error message is indicating that there is no constructor for the class "node" that takes a "void*" parameter. This means that there is likely a line of code that is attempting to create a new instance of the "node" class using a "void*" as the argument, but this is not a valid argument type for the constructor.

To fix this error, you will need to modify the line of code that is creating the new "node" instance to use a valid argument type for the constructor. If you are unsure what the correct argument type should be, you may need to review the documentation for the "node" class or consult with other members of your development team.
