Can not use opencode --port

[CamaleH]

Description

opencode --port just quit and return a {}. But opencode is fine.

System:

$ uname -a
Linux FA 6.12.73+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.73-1 (2026-02-17) x86_64 GNU/Linux

opencode --port logs (hide some privacy):

opencode logs, startup and then /exit (hide some privacy):

It's seem that two logs are same.

Can anyone tell me how to debug it?
