Bitbucket Agentic Pipelines with Codex Error

[NghiaLQ]

Hi everyone,

I'm using Bitbucket Agentic Pipelines with provider: codex. My pipeline configuration appears to be correct:

• OPENAI_API_KEY is configured as a secured Repository Variable.
• The variable is successfully available inside the pipeline (OPENAI_API_KEY is available).
• My pipeline can successfully clone another private repository before starting the agent.
• The Codex agent starts correctly (codex-acp 0.16.0).
• OpenAI provider has already been enabled at the Workspace level.

However, immediately after the agent starts, it fails during session creation with:

session creation error: {"code":-32000,"message":"Authentication required"}

The agent reports that OPENAI_API_KEY is a supported authentication method, but it never attempts the review and no additional authentication details are logged.

Is this a known issue with codex-acp 0.16.0, or is there any additional requirement for Agentic Pipelines to create a Codex session beyond providing OPENAI_API_KEY?

Any guidance would be greatly appreciated. Thanks!
