@Marvin I am running a test with pytest and it fails with the following error: ../../usr/local/lib/python3.10/site-packages/prefect/tasks.py:332 /usr/local/lib/python3.10/site-packages/prefect/tasks.py332 UserWarning: A task named 'asdfklasjf;' and defined at '/app/volitioniq/backend/workflows_2/sanity_checks.py:9' conflicts with another task.

parameter in the task definition:

warnings.warn( How can I fix it?

The error you are encountering is due to duplicate task names in your Prefect flow, which trigger a warning. To resolve this issue, you should specify unique names for each task. Below is an example on how to do this: Modify your task definitions to include unique names:

python
from prefect import flow, task

# Example task with a unique name
@task(name='task_unique_name1')
def task1():
    pass

@task(name='task_unique_name2')
def task2():
    pass

@flow
def my_flow():
    task1()
    task2()

if __name__ == "__main__":
    my_flow()

Replace

task_unique_name1

and

task_unique_name2

with appropriate unique names for your tasks. You can find more examples here. This should suppress the warnings and prevent conflicts between your task definitions. If you have any more questions or need further assistance, feel free to ask!

@Marvin They have unique names. Do I need to do something else if one task is called inside the other?

The issue you're encountering might not just be about unique names but could also be related to how tasks are being called within one another. Prefect's task system should handle nested tasks gracefully, so long as their names are unique and do not conflict. Here are a few additional steps you can take to troubleshoot and resolve the issue: 1. Ensure Unique Names: Double-check that all your tasks, including nested tasks, have truly unique names. 2. Refactor Nested Tasks: If you have tasks calling other tasks, ensure that each task is explicitly defined and invoked correctly within the flow. Here's an example:

python
from prefect import flow, task

@task(name='parent_task')
def parent():
    child1.run()
    child2.run()

@task(name='child_task1')
def child1():
    pass

@task(name='child_task2')
def child2():
    pass

@flow
def my_flow():
    parent()

if __name__ == "__main__":
    my_flow()

3. Debugging: Use logging to ensure that the tasks are getting unique names assigned dynamically and that the execution context isn't unintentionally triggering the warnings. If these steps do not resolve the issue, it could be beneficial to review Prefect's documentation on task naming and potential limitations with nested tasks more closely. You may also want to take a look at Prefect's community forums or GitHub issues for additional insights. If you need a deeper dive or have a more specific context, including the exact code could provide more clues. If the error persists, contacting Prefect support might be a good step.
