Chat Completions 上游 Base URL 不能为空

Error message

Chat Completions 上游 Base URL 不能为空

What it means

Thrown by open_chat_completions_proxy_request in crates/codex-plus-core/src/protocol_proxy.rs when the active relay profile is configured for the Chat Completions protocol but its base_url field is empty (or whitespace-only). Without a base URL the proxy cannot construct the upstream chat completions URL, so it aborts before sending anything.

Solutions

1. Open the active provider profile and fill in the upstream Base URL (e.g. https://api.vendor.com)
2. Ensure trailing slashes are fine (they are trimmed) but the URL must be non-empty and should include scheme and host
3. If importing from a share link, include the baseUrl query parameter

fn chat_relay_ready(relay: &RelayProfile) -> bool {
    relay.protocol == RelayProtocol::ChatCompletions && !relay.base_url.trim().is_empty()
}

When it happens

Trigger: Calling the chat completions proxy with an active ChatCompletions profile whose base_url was never filled in or was cleared; importing a provider definition that omitted baseUrl; settings file edited by hand leaving an empty string.

Common situations: Newly created provider profile saved before entering the endpoint; profile import from URL/query missing the baseUrl parameter; user cleared the field intending to switch providers later but the profile stayed active.
