`[object Object]` error output when running opencode over SSH

[nicehiro]

Description

Hi,

When running opencode via SSH on a remote server, the application outputs [object Object] instead of a proper error message or UI. Additionally, terminal escape sequences are not handled correctly, resulting in garbled output.

OpenCode version

1.0.134

Steps to reproduce

1. On Ubuntu 20 docker image, install opencode using: curl -fsSL https://opencode.ai/install | bash
2. Run opencode --print-logs --log-level DEBUG

[object Object]

Operating System

Ubuntu 22.04

Terminal

Using ghostty on MacOS to connect remote by ssh

This issue might be a duplicate of existing issues. Please check:

• Phantom input on startup again. #4430: Phantom input on startup when running over SSH (Windows Terminal -> Remote SSH)

• Bash commands not working in ssh session #3320: Bash commands not working in SSH session
• Theme issue #4517: Theme and terminal output issues on macOS

These issues also report SSH connection problems with terminal escape sequences and output corruption. The [object Object] error and garbled escape sequences you're seeing may be related to how opentui handles terminal detection and output formatting over SSH.

Feel free to ignore if none of these address your specific case.

I encountered this error even though I wasn't using SSH.

The error on my end occurred because I had a network proxy enabled.
The error likely originates from this location: https://github.com/sst/opencode/blob/dev/packages/sdk/js/src/v2/gen/client/client.gen.ts#L196

Same here. I also have a local proxy set.

[junjieit]

You can bypass the local address first.

export NO_PROXY=localhost,127.0.0.1,::1

Thanks for the suggestion. However, my situation is a bit different — I actually need the proxy to access the full network (e.g., npm registries and other external resources).
If I set NO_PROXY, the opencode CLI itself seems to work, but it still fails to launch properly because some dependencies can't be downloaded without the proxy.

same problem here?

timiil@tim-work:~$ opencode --print-logs --log-level DEBUG
INFO  2025-12-24T03:39:13 +175ms service=default version=1.0.193 args=["--print-logs","--log-level","DEBUG"] opencode

in a new wsl ubuntu 24.04.
thanks for help

very strange, ssh from a lan computer and start opencode is OK. the problem is related by Terminal ?

[nicehiro]

@timiil I guess the problem is related to using proxy.

I have following configs in my .bashrc as here

export HTTP_PROXY=xxx
export HTTPS_PROXY=xxx
export NO_PROXY=localhost,127.0.0.1

And also I need to set:

export OPENCODE_DISABLE_DEFAULT_PLUGINS=1

And now I can use opencode.
