@Marvin I want to raise an exception and pass a message

In Prefect, you can raise exceptions with a message by using the

PrefectException

class or any of its subclasses. Here's a basic example of how you might raise an exception with a message:

python
from prefect.exceptions import PrefectException

def my_function():
    raise PrefectException("This is a custom exception message")

my_function()

Relevant links: - Prefect exceptions source code This code snippet raises a

PrefectException

with a custom message. You can replace

PrefectException

with any specific subclass like

SerializationError

,

ConfigurationError

, etc., depending on the context of your error.
