Check the current user and directory

output = client.execute_command("whoami && pwd")
print(output)but i get some log2026-01-14 09:01:52,302 | INFO | agentcube.code_interpreter | Creating new session...

Start with the reproduction in /app/test_code_interpreter.py, then trace the request through agentcube/code_interpreter.py and agentcube/clients/data_plane.py. Inspect the failing POST to the code-interpreter invocation endpoint and the returned 502 response. Done means the reported SDK command completes successfully or the failure is clearly surfaced with an actionable cause.
