Error: thread/list failed during TUI session lookup

TL;DR

The issue may be resolved by checking the thread ID and TUI session configuration to ensure proper lookup and handling during the resume operation.

Guidance

• Verify that the thread ID 019d95e8-55f6-7f00-9595-732959b9ab0d is correctly formatted and valid for the gpt-5.4 model.
• Check the TUI session configuration to ensure it is properly set up for the Codex CLI version 0.121.0 and the pro subscription.
• Investigate if there are any known issues or limitations with the gpt-5.4 model that could be causing the thread/list failure during TUI session lookup.
• Test the /resume command with a different thread ID to see if the issue is specific to the uploaded thread.
