CodeX 401 Issue

Recently, we have received feedback from some users that the latest version of CodeX suddenly reports a 401 error. This may be due to a change in the APIKey authentication method in the latest version. The solution is:

Enter npx omgvibe in the terminal to reconfigure your codex via our one-click script

Alternatively, you can manually modify ~/.codex/config.toml

In the following section, define your APIKey using experimental_bearer_token. Example:

[model_providers.omg]

name = "omg"
base_url = "https://apic1.ohmycdn.com/v1"
wire_api = "responses"
experimental_bearer_token = "sk-x"
