Amazon Rekognition - CreateUserCommand InvalidParameterException: Request has invalid parameters

Question

Hello all,

While using Amazon Rekognition APIs we are getting error as `InvalidParameterException: Request has invalid parameters` when using `CreateUserCommand` API.

Other few commands are working - eg: `ListCollectionsCommand, ListUsersCommand`

More details are as
- Using node v18.16.0 (npm v9.5.1)
- Using nestjs
- Using "@aws-sdk/client-rekognition": "^3.409.0",

Sample code as

```
import { RekognitionClient } from "@aws-sdk/client-rekognition";
import { CreateCollectionCommand, ListCollectionsCommand, CreateUserCommand, ListUsersCommand,  } from  "@aws-sdk/client-rekognition";

// Init client
this.rekognition = new RekognitionClient({
    region: this.region,
    credentials: {
        secretAccessKey: this.secretAccessKey,
        accessKeyId: this.accessKeyId,
    },
});

// Call create user API
const createUserParams = {
    CollectionId: collectionId,
    UserId: userId,
    ClientRequestToken: 'dev' + new Date().getTime().toString()
};

/*
Where input sent is as
{
  CollectionId: 'test_dev',
  UserId: '1',
  ClientRequestToken: 'dev1694588820574'
}
*/

const createUserResponse =  await this.rekognition.send(new CreateUserCommand(createUserParams));

```

**Getting error as**

```

  },

}
```

- Tried with AWS SDK 2 and 3 - for both - getting same error
- Tried passing/not passing ClientRequestToken - for both - getting same error

Any help will be highly appreciated.

Thank you.

Hi,

can you try to add some letters before your '1' as UserId like 'user1'. This parameter is supposed to be a string. Your '1' is clearly a string but you may want to see what happens if you add some alphabetical chars.

Best.

Hi,

Several things to check:
1. Is CollectionID: "test_dev" exist?
2. Is UserId: "1" unique?

So far, I do not have other ideas about what could be wrong. Here is piece of documentation, maybe you find anything here:
https://docs.aws.amazon.com/en_us/AWSJavaScriptSDK/v3/latest/clients/client-rekognition/interfaces/createusercommandinput.html#userid-1
