aws_ssm.Connection._get_boto_client lose access_key, token when using aws profile

[dlscjf151]

Summary

I'm using ansible with aws ssm connection. I authenticated with aws credential profile, but encountered error on s3 client initializing

....

    File "/.venv/lib/python3.11/site-packages/botocore/signers.py", line 199, in sign
    auth.add_auth(request)
  File "/.venv/lib/python3.11/site-packages/botocore/auth.py", line 437, in add_auth
    self._inject_signature_to_request(request, signature)
  File "/.venv/lib/python3.11/site-packages/botocore/auth.py", line 440, in _inject_signature_to_request
    auth_str = ['AWS4-HMAC-SHA256 Credential=%s' % self.scope(request)]
                                                   ^^^^^^^^^^^^^^^^^^^
  File "/.venv/lib/python3.11/site-packages/botocore/auth.py", line 388, in scope
    print('/'.join(scope))
          ^^^^^^^^^^^^^^^
TypeError: sequence item 0: expected str instance, NoneType found
fatal: [*************]: FAILED! => {
    "msg": "Unexpected failure during module execution: sequence item 0: expected str instance, NoneType found",
    "stdout": ""
}

I printed debug log at fail point, access_key and token was None

ReadOnlyCredentials(access_key=None, secret_key='******************', token=None)

Because of this, scope becomes [None, '20240514', 'ap-northeast-2', 's3', 'aws4_request'] and raise error doing join None type
