What is expected?

The number or expression on one side of the equal sign should have the same value as the number or expression on the other side of the equal sign.

What is actually happening?

When I tried to build projects, the console reports error: no match for ‘operator=’

error: no match for ‘operator=’ (operand types are ‘object_msgs::DetectObjectRequest_<std::allocator<void> >::_image_paths_type {aka std::vector<std::__cxx11::basic_string<char> >}’ and ‘std::__cxx11::string {aka std::__cxx11::basic_string<char>}’)
   srv.request.image_paths = image_path;
                             ^~~~~~~~~~

value name	type
