Hello, all. I’m trying to build a deployment but getting this error:

Script at 'prefect/data_quality_scan.py' encountered an exception: TypeError("cannot pickle 'classmethod' 
object")

I have a Python file at ~/prefect/data_quality_scan.py that looks like this:

from prefect import flow  # type: ignore
from prefect.context import get_run_context  # type: ignore
from prefect_soda_core.soda_configuration import SodaConfiguration  # type: ignore
from prefect_soda_core.sodacl_check import SodaCLCheck  # type: ignore
from prefect_soda_core.tasks import soda_scan_execute  # type: ignore


@flow
def run_soda_scan():
        soda_configuration_block = SodaConfiguration(
                configuration_yaml_path="./soda/configuration.yaml"
        )
        soda_check_block = SodaCLCheck(sodacl_yaml_path="./soda/checks.yaml")

        # Using the flow_run_name as the name of the file to store the scan results
        flow_run_name = get_run_context().flow_run.name
        scan_results_file_path = f"{flow_run_name}.json"

        return soda_scan_execute(
                data_source_name="bigquery_connection",
                configuration=soda_configuration_block,
                checks=soda_check_block,
                variables={"var": "value"},
                scan_results_file=scan_results_file_path,
                verbose=True,
                return_scan_result_file_content=False,
        )


run_soda_scan()

I was able to build this deployment in the past but I just created a new environment and

pip

installed all of the dependencies I need. Now, I cannot build the deployment at all.
