velox_sort_benchmark test failed to execute RealWorldData_stdSort

Bug description

I build velox and velox benchmark and try to run velox_sort_benchmark. However, I didn't get RealWorldData_stdSort test result.
I copied parquet file cp ./velox/dwio/parquet/tests/examples/str_sort.parquet ../examples/
./_build/release/velox/exec/benchmarks/velox_sort_benchmark

System information

It could be reproduced on x86 or arm platform.

Relevant logs

It seems that if fail when running this line:
std::vector<std::optional<StringView>> stdVector(querySigCol->size());
in RowContainerSortBenchmark.cpp

It seems that when cast data->as()->childAt(0) to data->as()->childAt(0)->asFlatVector(), which is from VARCHAR to FlatVector, the value will be changed from size 1000 to null.
