This is a heap dump filename with a specific PID, meaning a heap dump was taken during development. Confirm the dump file itself is not tracked in the repository (git ls-files | grep hprof). The gitignore entry should use a wildcard (*.hprof) to catch any future dump rather than a single named file.

Missing nullable = false. A just-constructed OfficialBotAccount starts with token = uninitialized, and AccountService does two separate persist() calls to work around this. Add nullable = false and generate the token before the first persist to collapse it to one round-trip and make the constraint explicit at the DB level.

Is it okay to leave it like that?

Same two-persist pattern. The root cause is that bot.id is not available before the first persist(). Either use a pre-assigned UUID (@Id with UUID.randomUUID() before persist) or derive the token from a field that doesn't require a DB round-trip. Two flushes per creation is a correctness risk under failure: if the second persist fails, the entity exists without a valid token.
