Comprehend Entities language

Question

Hello,

In Java AWS SDK is there mandatory the language parameter when `Comprehend.getEntities` is invoked ?   
If language is not specified, will Comprehend.Entities detect the language, or which will be the behaviour ?

Thank you,

Accepted Answer

Language must be specified when using the pretrained model.
```
aws comprehend detect-entities --text "hello"

An error occurred (ValidationException) when calling the DetectEntities operation: Value 'null' at 'languageCode'failed to satisfy constraint: Member must satisfy enum value set: [ar, hi, ko, zh-TW, zh, ja, en, de, it, fr, pt, es]
```

If using your own custom model, the language will be detected from the custom model.
