Yes, there are a couple of ways to handle this in Prefect 3.x. The most straightforward approach is to use the

allow_failure

function, which lets you specify that certain tasks can fail without blocking the flow. Here's how you can do it:

python
from prefect import flow, task, allow_failure

@task
def task_that_might_fail():
    # This task might fail during materialization
    result = some_operation()
    return result

@flow
def my_flow():
    # Wrap the task with allow_failure
    result = allow_failure(task_that_might_fail())
    
    # Flow continues even if task_that_might_fail fails
    print("Flow continues!")

Alternatively, you can handle the materialization failure explicitly within the task using a try/except block:

python
from prefect import flow, task

@task
def task_with_handled_materialization():
    try:
        result = some_operation()
        return result
    except Exception as e:
        # Log the error but don't raise it
        print(f"Materialization failed: {e}")
        return None

@flow
def my_flow():
    result = task_with_handled_materialization()
    # Flow continues regardless of materialization failure
    print("Flow continues!")

The

allow_failure

approach is generally cleaner and more idiomatic in Prefect, as it makes the intention clear at the flow level rather than hiding the failure handling inside the task implementation. Remember that while these approaches allow the flow to continue, the task will still be marked as failed in the UI, and you might want to add appropriate logging or monitoring to keep track of these failures.
