Error decoding response body with WorkOS redirect after sign in.

Start by reproducing the WorkOS redirect sign-in flow on Linux with Codex CLI 0.145.0 and capture where response-body decoding fails. Trace the authentication redirect and response decoding entry points; done means sign-in completes without the decoding error. No source files or tests are named in the report, so locating the relevant code will require repository exploration.

What version of Codex CLI is running?

0.145.0

What subscription do you have?

gpt-5.6-sol high

What platform is your computer?

What issue are you seeing?

I was trying to implement auth for a desktop Rust + Tauri + React app with WorkOS. Codex struggled to get this correct and I am still having persistent errors. Could not reach WorkOS: error decoding response body.

What steps can reproduce the bug?

Uploaded thread: 019f8bc1-3520-7572-b82b-78ff3802ceba

What is the expected behavior?

I expected the redirect to go back to the main page of the app after sign in. That did not happen.
