AWS Chime Meeting transcription - EngineTranscribeSettings

Question

Hello,

I would like to start meeting transcription with automatic language detection. According to the documentation [link](https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_meeting-chime_EngineTranscribeSettings.html), I set up the configuration:

```
StartMeetingTranscriptionCommand({
      MeetingId: meetingId,
      TranscriptionConfiguration: {
        EngineTranscribeSettings: {
          IdentifyLanguage: true,
          LanguageOptions: "en-US,de-DE",
          Region: 'us-east-1',
          EnableChannelIdentification: true
        }
      }
    });
```
When I execute the command I see error 
```
 "message": "1 validation error detected: Value null at 'transcriptionConfiguration.engineTranscribeSettings.languageCode' failed to satisfy constraint: Member must not be null"
```
In the docs I see that this field is not required.

Where is the issue? I would be grateful for any suggestion.

Answer

We have a new API namespace for the Amazon Chime APIs. We only add or update meeting APIs in the "Amazon Chime SDK Meetings" namespace. We fully support the meeting APIs in the "Amazon Chime" namespace, but they remain as-is. Language detection is something that was added only in the new namespace.

I _suspect_ that you are still using the old namespace.

For example, looking at the documentation for EngineTranscribeSettings (which is in two places -- one for each namespace) you can see that LanguageCode is required only in the old namespace and IdentifyLanguage is only valid in the new namespace.

* Old options:  https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_EngineTranscribeSettings.html
* New options: https://docs.aws.amazon.com/chime-sdk/latest/APIReference/API_meeting-chime_EngineTranscribeSettings.html

If you want to use automatic language detection, you will need to move to the new namespace. Documentation for doing so are here: https://docs.aws.amazon.com/chime-sdk/latest/dg/meeting-namespace-migration.html
