Hi,

Looks like you are not using Lex V2 endpoint (https://runtime-v2-lex.us-east-1.amazonaws.com/bot/botname/alias/aliasname/user/userid/text) as expected. In order to access Lex V2 Recognize Text API, you need to send a post request to the endpoint https://runtime-v2-lex.us-east-1.amazonaws.com//bots/botId/botAliases/botAliasId/botLocales/localeId/sessions/sessionId/text. I would recommend following [this](https://docs.aws.amazon.com/lexv2/latest/APIReference/API_runtime_RecognizeText.html#API_runtime_RecognizeText_RequestSyntax) documentation closely to hit RecognizeText API through postman or any other http client.

Another option is to AWS CLI.

Sample command to hit RecognizeText API

```
aws lexv2-runtime recognize-text --bot-id “7TBXBYVXOE” --bot-alias-id “TSTALIASID” --locale-id “en_US” --session-id “test_123” --region us-east-1 --text “book hotel”
```

Related AWS CLI documentation can be found [here](https://docs.aws.amazon.com/cli/latest/reference/lexv2-runtime/recognize-text.html)

Hi,

One possibility is you may have created the bot using [Lex V2 console ](https://us-east-1.console.aws.amazon.com/lexv2/home?region=us-east-1#bots) which is the default interface for creating bots. And you are trying to access this bot through Lex V1 runtime APIs (https://runtime.lex.us-east-1.amazonaws.com/bot/botname/alias/aliasname/user/useid/text). Can you please try using [Lex V2 runtime endpoint](https://docs.aws.amazon.com/general/latest/gr/lex.html#lexv2_region) as documented [here](https://docs.aws.amazon.com/lexv2/latest/APIReference/API_runtime_RecognizeText.html).
