Bug: getInsertID is only returning 0 when using the Save() method about codeigniter4 HOT 3 CLOSED

Cannot reproduce with CI 4.5.1 or 4.4.8.

I see int(5):

    public function testInsertID(): void
    {
        $data = [
            'name'        => 'Apprentice',
            'description' => 'That thing you do.',
        ];

        $this->createModel(JobModel::class);
        $this->model->protect(false)->save($data);

        $lastInsertId = $this->model->getInsertID();
        var_dump($lastInsertId); exit;

        $this->seeInDatabase('job', ['id' => $lastInsertId]);
    }

The work around we are currently having to use is
to check if we have an primary key id, then calling the insert or update function separately which works fine.

I don't know why the workaround is needed, because it is what the save() method does:
