Hello, currently migrating from prefect v1 to v2 and I'm trying to find the way of passing this argument to a generic task as I was doing it on v1. Is it possible on v2?

task_args={"name": "current-task-run-name"}

This should be an option I think unless I misunderstand your question - https://docs.prefect.io/api-ref/prefect/tasks/ Task_run_name is a field

Yeah, I've seen this, but I try adding the task_run_name parameter when calling the task and I get:

got an unexpected keyword argument 'task_run_name'.

How are you setting it? It’s in the object, so that’s surprising. https://github.com/PrefectHQ/prefect/blob/main/src/prefect/tasks.py#L176

yeah, I know, I've been through the code too 😕 I just add

task_run_name="task_name"

as a parameter to the task

Have you tried using it like:

@task(task_run_name="task_name")

or is that what you mean?

no, what I'm trying to do is the following. I define a task:

@task(name="generic-task-name")
def task_a(name: str):
    print(f"Hello {name}")

and then call it withing the flow like this:

@flow(name="Amazing-flow")
def my_flow():
    task_a("Andres",task_run_name="task-to-say-hello-to-andres")

Without explicitly testing it myself, I don’t know . Looking at the error you’re receiving, it’s because

task_a(name: str)

does not have

task_run_name

defined, so you’re passing an argument that only exists in the wrapper
