@amosbird It seems we have some bug with nullable_serialization_version='allow_sparse';

[amosbird]

Lemme try to reproduce it and take a look at fixing it.

With the current test (https://github.com/ClickHouse/ClickHouse/pull/92042/changes#diff-8a09ed4f332d8026c2f08c278ba725e0642e657f7f9cdb7e34fceab2a0e54682) it always reproduces. It seems related to WHERE t.a.size = 1

Closed in favor of #92060
