Amazon Rekognition - CreateUserCommand InvalidParameterException: Request has invalid parameters


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.

  • Could you share the account Id, region and timestamp for this call to troubleshoot what we received at the service end?

  • @Venkat is it safe to share account ID here?

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.

  • Heh, also thought about that and even checked the SDK source code but not an expert in JS, just expecting that something passed as string will be treated as string :)

  • Tried this. This seems to work, thank you.



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:

  • Thank you for your answer. I can confirm - 1 - collection exists 2 - the user being created is not present in the collection (and would be unique)
