soci into empty vector triggers error Vectors of size 0 are not allowed

[yihuajack]

According to the documentation https://soci.sourceforge.net/doc/master/binding/, I write

std::vector<int> ids;
sql << "SELECT ID FROM TABLE", soci::into(ids); 

It triggers soci_error("Vectors of size 0 are not allowed.") in src/backends/.../vector-into-type.cpp
However, if I write

std::vector<int> ids(1);

or initialize the capacity to any size larger than 0 the code can run. Is the error intentionally designed to throw if the size of the vector is 0? If so, why is it needed since into will automatically resize the vector?
