error: invalid conversion from 'my_type *' to 'int' [-fpermissive]

Running my code returns this error written in the title. I do not know what to do to solve it, because if you see the code, of course the parameter type is BlockGraph and not int . When I put an integer value in place of block, no error is returned.

The IDE also returns note: initializing argument 1 of 'BlockGraph::BlockGraph(int)'|
