Error message

minimax tts: request: %w

What it means

This error wraps a failure of m.Client.Do(req) — the actual HTTP round-trip to MiniMax's /v1/t2a_v2 endpoint. It covers connection failures, DNS errors, TLS problems, and context cancellation/deadline exceeded during the request. No HTTP response was received, so the failure is at the network/transport layer.

Solutions

1. Verify outbound connectivity to the MiniMax host: curl -v <base_url>/v1/t2a_v2 from the same machine.
2. Unwrap the error and check for context.DeadlineExceeded / context.Canceled; if deadline, raise the client timeout.
3. Check proxy environment variables (HTTPS_PROXY/HTTP_PROXY) and TLS setup if behind a corporate proxy.
4. Fix the base_url in config.toml if it points at an unreachable or misspelled host.
5. For transient network errors, retry Synthesize with backoff.

if u, err := url.Parse(cfg.BaseURL); err != nil || u.Host == "" { return fmt.Errorf("invalid base_url") }
// smoke-test reachability at startup
resp, err := http.DefaultClient.Get(cfg.BaseURL)

audio, format, err := tts.Synthesize(ctx, text, voice)
if err != nil && strings.Contains(err.Error(), "minimax tts: request:") {
    if ne, ok := err.(*net.OpError); ok || errors.Is(err, context.DeadlineExceeded) {
        // transient network: retry with backoff
    }
}

When it happens

Trigger: MiniMax API host unreachable or DNS resolution fails; TLS handshake error (bad proxy, clock skew, blocked egress); ctx deadline exceeded while the request was in flight; network drop mid-request.

Common situations: Running in a container or CI without outbound internet access; corporate proxy not configured (HTTPS_PROXY unset); base_url pointing at a wrong/unreachable host; too-short HTTP client timeout for TTS generation.
