ML Kit ASR error: Error code:40,subError code:3005,errorMessage: Service unavailable

I've been developing a demo for speech recognition and ran into an issue. Could anyone help me? I called startRecognizing interface and received an onError callback (Error 11203, subError 3005, errorMessage: service unavailable), see screenshot:

I followed the document , My code:

// Create an Intent to set parameters.
val mSpeechRecognizerIntent = Intent(MLAsrConstants.ACTION_HMS_ASR_SPEECH)
// Use Intent for recognition parameter settings.
mSpeechRecognizerIntent 
// Set the language that can be recognized to English. If this parameter is not set, English is recognized by default. Example: "zh-CN": Chinese; "en-US": English; "fr-FR": French; "es-ES": Spanish; "de-DE": German; "it-IT": Italian; "ar": Arabic; "th_TH": Thai; "ms_MY": Malay; "fil_PH": Filipino.
.putExtra(MLAsrConstants.LANGUAGE, "en-US") // Set to return the recognition result along with the speech. If you ignore the setting, this mode is used by default. Options are as follows:
// MLAsrConstants.FEATURE_WORDFLUX: Recognizes and returns texts through onRecognizingResults.
// MLAsrConstants.FEATURE_ALLINONE: After the recognition is complete, texts are returned through onResults.
.putExtra(MLAsrConstants.FEATURE, MLAsrConstants.FEATURE_WORDFLUX) // Set the application scenario. MLAsrConstants.SCENES_SHOPPING indicates shopping, which is supported only for Chinese. Under this scenario, recognition for the name of Huawei products has been optimized.
.putExtra(MLAsrConstants.SCENES, MLAsrConstants.SCENES_SHOPPING)
// Start speech recognition.
mSpeechRecognizer.startRecognizing(mSpeechRecognizerIntent)

Do you have any idea why this could be happening? Please help, thanks!!

You need to change "en-US" to "zh-CN".

Or comment out ".putExtra(SCENES, SCENES_SHOPPING)":
