No dag run/context in task_instance_mutation_hook #60610
Description
Apache Airflow version
Other Airflow 3 version (please specify below)
If "Other Airflow 3 version" selected, which one?
3.1.3
What happened?
The task_instance_mutation_hook provides the TaskInstance object using which one should be able to call the dag_run or get_dagrun() to obtain the DagRun object but they return None. Also there is no way to obtain the context through this TaskInstance. So its not possible to implement logic that makes use of a Params value obtained from manual dag trigger configs.
What you think should happen instead?
task_instance_mutation_hook's TaskInstance should either give access to the valid DagRun.conf or the context object so the Param value passed from manual trigger can be read inside the hook. dag_run or get_dagrun() from the hook's TaskInstance should not return None or fail.
How to reproduce
Create a Param in the Dag code. Manually trigger the dag with the Advanced options and pass the Param value with your dag run. Try to access your passed Param value in the task_instance_mutation_hook.
