UI rendering issues after migrating to Airflow 3.0.3

[alexandervanloock]

Apache Airflow version

3.0.4

If "Other Airflow 2 version" selected, which one?

No response

What happened?

before version 3 dags where not versioned, it seems now that old tasks which were allready in the DAG are not available anymore in the main ui of the dag itself and logs are also lost

, it also renders the titles of the tasks weird, it is possible to find the old tasks in the task instance explorer

What you think should happen instead?

it seems the addition of versioning messes with the history, I dont know if it is something we just have to accept or if there is a deeper underlining issue

How to reproduce

have a dag with a Taskgroup and have runs on an old version of airflow
upgrade airflow to v3 and check UI

python:3.12.0-slim-bookworm

Having the same problem, what can be the issue?

[eladkal]

Does this happens for all dags? is there a reproduce example we can verify it?

[vatsrahul1001]

I followed the steps to reproduce in the issue but was not able to replicate it. @alexandervanloock, can you confirm if this is for a specific DAG?

[alexandervanloock]

Hi, no we have this on the majority of dags

the only difference I see is the versioning, from the moment the dags are scheduled regularly again the runs contain all the logs, the titles in the tree though keep being truncated

we are currently on airflow 3.0.3

Since you can still find the task instances in the table view it sounds to me like it's an issue with how we calculate task group states + version in /ti_summaries. cc: @dstandish
If you check the brower's Network tab, look for endpoints with the name of the dag_run_id and see if you can find the missing task instances
