@Marvin How do I get around this error? 'msg': 'Flow run parameters must be less than 512KB when serialized.'

The error you're encountering is due to the size of the parameters you're passing to your flow run in Prefect. The parameters cannot exceed 512KB in size when serialized. Here are a few things you can do: 1. Reduce the size of your parameters: If you're passing large data structures as parameters, consider reducing their size or passing only the necessary information. 2. Use type hints: Prefect allows you to use type hints in your flow functions. This provides a way of automatically coercing JSON provided values to their appropriate Python representation. For example, to automatically convert something to a datetime:

from prefect import flow
from datetime import datetime

@flow
def what_day_is_it(date: datetime = None):
    if date is None:
        date = datetime.utcnow()
    print(f"It was {date.strftime('%A')} on {date.isoformat()}")

what_day_is_it("2021-01-01T02:00:19.180906")  # It was Friday on 2021-01-01T02:00:19.180906

3. Validate your parameters: Parameters are validated before a flow is run. If a flow call receives invalid parameters, a flow run is created in a Failed state. If a flow run for a deployment receives invalid parameters, it will move from a Pending state to a Failed state without entering a Running state. For more detailed information, you can refer to the Prefect documentation.
