TargetConfigs' credentials gets dropped upon loading a DbtCliProfile

from prefect import flow
from prefect_gcp import GcpCredentials

ENV = "abc"

@flow
def test_flow():
    credentials = GcpCredentials.load('gcp-credentials')

        'schema': f'zone_hawk_{ENV}',
        'project': 'my_gcp_project',
        'threads': 20,
        'credentials': credentials
    }

    bq_target_configs = BigQueryTargetConfigs(**bq_target_dict)
    bq_target_configs.save(f'bq-target-configs-{ENV}', overwrite=True)

    target_configs = BigQueryTargetConfigs.load(f'bq-target-configs-{ENV}')

    print(dbt_cli_profile)

Returns:

Expected:

DbtCliProfile(name='bigbird', target='abc', target_configs=BigQueryTargetConfigs(extras=None, type='bigquery', threads=20, project='my_gcp_project', credentials=GcpCredentials(service_account_file=None, service_account_info=SecretDict('{'type': '**********', 'auth_uri': '**********', 'client_id': '**********', 'token_uri': '**********', 'project_id': '**********', 'private_key': '**********', 'client_email': '**********', 'private_key_id': '**********', 'client_x509_cert_url': '**********', 'auth_provider_x509_cert_url': '**********'}'), project='myproject')), global_configs=None)
