What is the issue?
I was unable to get codex to connect with lm studio.
export CODEX_OSS_BASE_URL="http://localhost:1234/v1"
codex --oss -m "openai/gpt-oss-20b"
LM studio sees the connection attempt but it fails.
Pulling model openai/gpt-oss-20b...Error: OSS setup failed: Pull stream ended unexpectedly without success.
Asking chatgpt for assistance, it had me adjusting config.toml and no luck neither.
Where did you find it?
