AWS Javascript SDK PersonalizeRuntime getPersonalizedRanking does not return scores

Question

According to the documentation https://docs.aws.amazon.com/AWSJavaScriptSDK/latest/AWS/PersonalizeRuntime.html#getPersonalizedRanking-property
getPersonalizedRanking should return an array of objects that include both the itemId and score. When I use this function I only get the item ids, and no scores. Running this on the console gives me the same order of item ids and also includes the scores.

Is there something I'm missing or is this potentially a bug in the javascript sdk?

Here are my params:

```
{
  campaignArn: "removed",
  inputList: [
    "12-7-53",
    "170-7-53",
    "883-7-53",
  ],
  userId: "1317",
  context: {
  },
}
```
And the repsonse:
```
{
  personalizedRanking: [
    {
      itemId: "883-7-53",
    },
    {
      itemId: "170-7-53",
    },
    {
      itemId: "12-7-53",
    },
  ],
}
```

Accepted Answer

I was able to print out the scores for GetPersonalizedRanking with **AWS SDK JavaScript version 2.1404.0** and **Node version 20.3.1**, I ran the code below in my local environment:

const AWS = require('aws-sdk')

AWS.config.update({
      accessKeyId: 'INSERT-ACCESS-KEY',
      secretAccessKey: 'INSERT-SECRET-KEY',
      region: "us-east-1"
    })

const personalize = new AWS.PersonalizeRuntime();

var params = {
      campaignArn: "arn:aws:personalize:us-east-1:account:campaign/example-campaign-name",
      inputList: ['257', '201', '495', '399', '184', '919', '222', '227', '450', '151', '373', '380'],
      userId: '2', 
      context: {} 
    };

personalize.getPersonalizedRanking(params, (err,data) => {
      if(err){
        console.log(err);
      }else{
        console.log(JSON.stringify(data.personalizedRanking));
        const rankedItems = data.personalizedRanking.map  ((item) => item.itemId);
        console.log("OUTPUT " + rankedItems);
      }
    });

I then received an output with the scores, below is an example:

{
        "itemId": "495",
        "score": 0.988938,
        "promotionName": null
    }

I suggest checking the SDK and Node versions that you are using and try the versions I have used here to see if the scores will appear in the output. But should you still face an issue of scores being excluded in the response, then I would suggest raising a case with AWS Premium Support [1] for further troubleshooting to understand why the scores are not being passed.

I hope this helps.
