[Sealing Issue]SectorInfo could not be obtained through StateSectorGetInfo

Describe the problem
In the process of testing SubmitCommitAggregate, I encountered the problem that SectorInfo could not be obtained through StateSectorGetInfo.

Lotus miner logs
miner report an error: "proof validation failed, sector not found in sector set after cron"

After handleSubmitCommitAggregate aggregation is successfully executed, when it is executed to handleCommitWait, because si is nil.

si, err := m.api.StateSectorGetInfo(ctx.Context(), m.maddr, sector.SectorNumber, mw.TipSetTok)
	if err != nil {
		return ctx.Send(SectorCommitFailed{xerrors.Errorf("proof validation failed, calling StateSectorGetInfo: %w", err)})
	}
	if si == nil { // todo
		return ctx.Send(SectorCommitFailed{xerrors.Errorf("proof validation failed, sector not found in sector set after cron")})
	}

I'm not sure what caused this, I haven't encountered this problem before. and under what circumstances will ProveCommitSector cause SectorInfo to be nil?

well the sector becomes active after the call to ConfirmSectorProofsValid succeeds which happens during cron. That can fail for any number of reasons (insufficient funds / invalid proof).
