Notes:
This seems to be related to when the task instances are being stored in the
`task_instance` table, the `dag_version_id` is not properly assigned to them,
which is likely causing the `dag_version` data to not be pulled in with the
`task_instance` during the API call.
The one task instance with the correct version appearing has the
`dag_version_id` set in the DB, but the others that are showing `vundefined`
have the `dag_version_id` set to `[NULL]`.
I also found this here in the `airflow/jobs/scheduler_job_runner.py` file
and seeing that only TIs in State.unfinished are updated with the
`dag_version_id`
eg.
```py
# Select all TIs in State.unfinished and update the dag_version_id
for ti in dag_run.task_instances:
if ti.state in State.unfinished:
ti.dag_version = latest_dag_version
```
I am a FE dev, so this is beyond my expertise, but I would really like to
keep an eye on this to see how this is resolved.
