freyrsae opened a new issue, #24990:
URL: https://github.com/apache/airflow/issues/24990
### Apache Airflow version
2.2.5
### What happened
We have slack alerting on failure enabled in our DAG and use
`context.get('task_instance')` to customise the error message but it is usually
the wrong task_instance we get. Seems very familiar to
https://github.com/apache/airflow/discussions/19371
### What you think should happen instead
I should get the task instance of the task that failed, not just some task
in the dag.
### How to reproduce

### Operating System

### Versions of Apache Airflow Providers

### Deployment
