when running with ollama, tools dont work

[MasoudKarimnia03]

hello,
i'm trying to get codex 0.44.0 to work with ollama , running gpt-oss-20b locally.
i'm running all this in ubuntu 24.04 natively (not wsl), Linux 6.8.0-85-generic x86_64 x86_64

when i ask the agent any questions , i see this in the transcripts:

We must explain codebase. Let's inspect repo.We must explain codebase. Let's inspect repo.

We need to show tree maybe using print_tree? repository browser may support print_tree? According to function name print_tree is from repo_browser. But it's missing? There's error unsupported. maybe use find? Let's try again.We need to show tree maybe using print_tree? repository browser

i've set approvals to full auto, not sure what else i'm supposed to do. any help would be appreciated.

ollama works fine when i run it through the terminal independently or via openweb-ui.
