Hitting TypeError when trying to fetch secrets in python 3.8

Hi Guys

I am facing an issue while using the sdk for python version 3.8.
Same piece of code runs fine without any issues for Python 3.6.

import oci
region="test"
config_file=".oci_config_file"
config = oci.config.from_file(config_file, profile_name=region.upper())
vault_client = oci.vault.VaultsClient(config)
argus_compartment_id=config.get("argus_comp_id")
vault_id=config.get("vault_id")
secret_list = vault_client.list_secrets(name = "Dummy_secret", compartment_id=argus_compartment_id, vault_id=vault_id, lifecycle_state="ACTIVE")

Error:

When Tried with version 3.6, it runs absolutely smooth.

Awaiting a response on this.

Start by reproducing the Python 3.8 failure through oci/vault/vaults_client.py and trace the request path into oci/base_client.py, including the vendored requests and urllib3 layers shown in the traceback. Compare the Python 3.6 and 3.8 environments; done means list_secrets completes successfully on Python 3.8 with regression coverage if the repository has tests for this path.
