What issue are you seeing?

Issue:
When I click Run now on a Codex Desktop automation, Codex creates a session file, but the session contains only session_meta and never executes the automation prompt.

Evidence:

• Direct Gmail connector works from normal chat.
• Direct Gmail send works from normal chat.
• Cron automation "Gmail Automation Smoke Test" creates a session:

C:\Users\.codex\sessions\2026\05\10\rollout-2026-05-10T20-11-36-019e10f1-1776-7123-8559-a79e8efa5342.jsonl

• That file has exactly 1 JSONL entry: session_meta only.
• No user prompt, no tool calls, no final output, no error.
• Heartbeat automation also did not fire.

Expected:
Run Now should execute the automation prompt.

Actual:
Run Now creates a session, then nothing happens.

What steps can reproduce the bug?

Create an automation to send an email using gmail.
