[Interest] can't dump QStringList with qDebug()

I'm porting my code to Qt6 (6.4.2) (from 5.15) and ran into this
mysterious problem; this code doesn't compile:
const auto connections = QSqlDatabase::connectionNames();
qDebug() << "Closing open connections:" << connections;
claiming that
../../../src/server/server_database.cpp:691:45: error: invalid operands
to binary expression ('QDebug' and 'const QList<QString>')
It then lists all the candidates, of which there are many. I have a
simple test program that compiles OK though.
The same occurs on both Visual Studio/Windows and gcc 10/Linux.
Am I missing an include or something?
