Said method passes down its diff input to mutate_internal(), after some std::ranges massaging. Said massaging is destructive -- it moves items from the diff. If the output range is iterated-over multiple times, only the first time will see the actual output, further iterations will get an empty range.
When trace-level logging is enabled, this is exactly what happens: mutate_internal() iterates over the range multiple times, first to log its content, then to pass it down the stack. This ends up resulting in an empty range being pased down and write handlers being created with nullopt optionals.

A follow-up stability fix for the test is also included.

Based on code-inspection, all versions are vulnerable, although <=6.2 use boost::ranges, not std::ranges.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
