Erroring about using push_back function in visual studio 2019 for Azure Kinect

问题

For line

body_result_json["joint_orientations"].push_back({          
    skeleton.joints[j].orientation.wxyz.w,                                                         
    skeleton.joints[j].orientation.wxyz.x,                                                      
    skeleton.joints[j].orientation.wxyz.y,                                                                    
    skeleton.joints[j].orientation.wxyz.z });

I got the error as below:

nlohmann::basic_json<std::map, std::vector, std::string, 
bool, int64_t, uint64_t, double, std::allocator, nlohmann::adl_serializer>" 
has no member "push_back" offline_processor
