sample code with OCISessionAuth raises issue

[streamnsight]

when runnign the sample code with OciSessionAuth() I get:

Traceback (most recent call last):
  File "/Users/epleroy/workspace/code/me/playground/test_langchain_oci_openai/langchain_oci_openai.py", line 21, in <module>
    http_client=httpx.Client(auth=OciSessionAuth()),
                                  ~~~~~~~~~~~~~~^^
  File "/Users/epleroy/workspace/code/me/playground/test_langchain_oci_openai/.venv/lib/python3.13/site-packages/oci_openai/oci_openai.py", line 175, in __init__
    token = self._load_token(config)

    token_file = config["security_token_file"]

providing profile name etc... doesn't help.
