get upload_config failed: %s

Error message

get upload_config failed: %s

What it means

The Doubao upload-config request returned a ResponseMetadata error other than 100028 (which is handled by token refresh), and the driver surfaces the backend's Message verbatim. This is the generic failure path for obtaining the upload address (host, store URI, slice size) required before any bytes are sent.

Solutions

1. Read the Message text — Doubao messages are usually descriptive (quota, permission, invalid params)
2. Retry after re-login if the message hints at auth even though code != 100028
3. Reduce concurrent upload threads (uploadThread setting) if the message indicates throttling
4. If it persistently fails with a fresh login, check the driver repo for API-contract updates

Example fix

// before
return fmt.Errorf("get upload_config failed: %s", configResp.ResponseMetadata.Error.Message)
// after
return fmt.Errorf("get upload_config failed: code=%d msg=%s (request_id: %s)",
	configResp.ResponseMetadata.Error.CodeN,
	configResp.ResponseMetadata.Error.Message,
	configResp.ResponseMetadata.RequestId)

if _, err := d.GetUserInfo(ctx); err != nil {
	return fmt.Errorf("doubao session invalid before upload: %w", err)
}

func isUploadConfigError(err error) bool {
	return err != nil && strings.Contains(err.Error(), "get upload_config failed")
}

if isUploadConfigError(err) {
	msg := extractMessage(err)
	if containsAny(msg, "limit", "frequent") { return backoffRetry(60*time.Second) }
	if containsAny(msg, "auth", "login") { return relogin() }
	return fail(err)
}

When it happens

Trigger: Calling getUploadConfig with a token whose Alice/Samantha credentials lack upload permission, a data type the backend rejects, quota/rate errors, or any non-100028 backend error code; also reached when 100028 occurs a second time after one refresh (tokenRefreshed already true).

Common situations: Cookie valid enough for listing but not for uploads; account storage full; too many concurrent uploads; Doubao app/API version change introducing new required parameters.
