taylorterwin opened a new issue, #34676:
URL: https://github.com/apache/airflow/issues/34676
### Apache Airflow version
2.7.1
### What happened
In the dbt Airflow provider code (referenced below), a field called
trigger_reason is mapped to the JSON cause key:value pair, that you would
directly set in Postman.
When trigger_reason is not set in Airflow (None) it defaults to creating a
calculated string:
```
```
if self.trigger_reason is None:
self.trigger_reason = (
f"Triggered via Apache Airflow by task {self.task_id!r} in
the {self.dag.dag_id} DAG."
)
```
I'm going to guess that in this case, the trigger_reason isn't set in the
airflow task, and therefore the task_id and the dag_id are both so long (?)
that they are causing this calculated string to exceed 255 characters.
That being said, we should handle this better and truncate it at 254
regardless.
code is here:
https://airflow.apache.org/docs/apache-airflow-providers-dbt-cloud/3.3.0/_modules/airflow/providers/dbt/cloud/operators/dbt.html
### What you think should happen instead
Basically the summary is that on this line;
https://github.com/apache/airflow/blob/bd512007e531bb58e86f8c1b8f84ac20e8e92d7c/airflow/providers/dbt/cloud/operators/dbt.py#L132
`cause ` needs to be limited to 255 characters
### How to reproduce
the trigger_reason creating a calculate string
def trigger_job_run(
self,
job_id: int,
cause: str,
account_id: Optional[int] = None,
steps_override: Optional[List[str]] = None,
schema_override: Optional[str] = None,
additional_run_config: Optional[Dict[str, Any]] = None,
) -> Response:
