Error when using custom provider w/ env var url

[frap129]

Pretty unique situation here causing this bug. My employer hosts a local proxy for llms, which I use as a custom provider in opencode. There are different endpoints for different regions and when your on internal vs external networks. Because of this, I use opencode's env var loading support in my config to change the base URL. In my opencode config, this is defined as "baseURL": "{env:CUSTOM_API_URL}",, and I can use the provider just fine. When checking the logs from dcp, it is filled with the following:

2025-11-25T18:53:46.057Z INFO  janitor: Model: custom/gemini-2.5-flash | source=config
2025-11-25T18:53:46.061Z ERROR janitor: Analysis failed | error="{env:CUSTOM_API_URL}/chat/completions" cannot be parsed as a URL.

I may look into fixing this myself if I get time, but wanted to report it first.

Thank you for the report! I'll look into this, I don't know much about how these custom providers work yet so it may take a minute, if you want to take a crack at it PRs are always welcome. In the meantime, does your employer only allow use of models served through this provider? If not you can pick a different provider/model in your dcp.jsonc.

No, we also get (limited) copilot requests, so I resolved it by switching to gpt-5-mini on copilot. Again not a huge issue, but thought it would be worth reporting.
