What version of Codex is running?
0.58.0
What subscription do you have?
ChatGPT Plus
Which model were you using?
gpt-5.1-codex
What platform is your computer?
Darwin 25.0.0 arm64 arm
What issue are you seeing?
The model hallucinated about how Firebase handle continueUrl in Firebase Authentication. It said Firebase will treat the query params in a continueUrl as a template and fill information in, such as oobCode. This is NOT true. The oobCode is only appended to the action handler URL.
What steps can reproduce the bug?
Uploaded thread: 019a818b-9791-70c1-b017-4aff64399fd9
What is the expected behavior?
The model should search the internet and refer to the official documentation (up-to-date: https://chatgpt.com/c/691ac8b4-c878-8323-a7df-3a929945ec87) instead of hallucinating. It should tell me to create my own hosted handler if I need to use the oobCode to render my elements.
