std::排序为排序自定义对象时出现的向量引发错误

我正在尝试使用std：：sort对已定义对象的向量进行排序。但是，我遇到了一长串错误。我试图从日志中发现一些东西并进行更改。 我相信比较运算符必须有一些东西。从日志中可以发现什么吗？！

std::vector<ShapeDescriptor> bins;
bins = objects.getBinsInRange(DEFAULT_BIN, cWest, endNorth);
// sort using a custom function object
std::sort(bins.begin(), bins.end(), 
[](ShapeDescriptor a, ShapeDescriptor b)
{return a.getPosition().x < b.getPosition().x;});

错误日志是
