Error message

api call: %w

What it means

Wraps a transport error from the raw SDK call p.client.Get("/open-apis/bot/v3/info") used by fetchBotOpenID to discover the bot's open_id. Thrown when the HTTP request to the Feishu bot-info API fails before a response can be parsed (network error, auth failure, client misconfiguration).

Solutions

Inspect the wrapped error for the exact transport cause.
Verify app_id/app_secret and that the correct API domain (.cn vs larksuite) is configured.
Ensure the lark client is created before fetchBotOpenID runs (check startup ordering).
Check host network/proxy access to the Feishu open API.

Defensive patterns

Strategy: fallback

Validate before calling

if p.client == nil {
    return errors.New("feishu: lark client not initialized before fetchBotOpenID")
}

Try / catch

openID, err := p.fetchBotOpenID()
if err != nil {
    slog.Warn("feishu: bot open_id unavailable, continuing without it", "err", err)
    openID = "" // degrade gracefully where open_id is optional
}

Prevention

Initialize the lark client before any bot-info API calls at startup.
Configure the correct API domain for your region (feishu.cn vs larksuite.com).
Treat bot open_id as optional metadata and degrade gracefully when unavailable.
Run connectivity checks (cc-connect doctor) before going live.

When it happens

Trigger: p.client.Get(context.Background(), "/open-apis/bot/v3/info", nil, larkcore.AccessTokenTypeTenant) returns err at platform/feishu/feishu.go:3815 — DNS/proxy failure, invalid tenant_access_token acquisition, or nil p.client during startup ordering issues.

Common situations: Platform starting before the lark client is fully initialized; wrong domain (feishu vs Lark) configured so the endpoint doesn't resolve; invalid app credentials; corporate firewall blocking open.feishu.cn.
