Unexpected Key 1-10 in params with translateText

Question

So I'm just running a function to translate text with AWS Translate. Here is my params and the call to the function:

const translate = new AWS.Translate({ apiVersion: '2017-07-01' });

const data = JSON.parse(event.body);

const params = {
  "TableName": "sites",
  "Item": {
    SourceLanguageCode: 'auto', /* required */
    TargetLanguageCode: data.TargetLanguageCode, /* required */
    Text: data.Text, /* required */
  }
};

const translated = await translate.translateText(params.Item.Text).promise();

If I console log params.item.text it outputs the right thing. But then when i run the translateText function I get the error

* UnexpectedParameter: Unexpected key '0' found in params
* UnexpectedParameter: Unexpected key '1' found in params
* UnexpectedParameter: Unexpected key '2' found in params
* UnexpectedParameter: Unexpected key '3' found in params
* UnexpectedParameter: Unexpected key '4' found in params
* UnexpectedParameter: Unexpected key '5' found in params
* UnexpectedParameter: Unexpected key '6' found in params
* UnexpectedParameter: Unexpected key '7' found in params
* UnexpectedParameter: Unexpected key '8' found in params
* UnexpectedParameter: Unexpected key '9' found in params
* UnexpectedParameter: Unexpected key '10' found in params

Here is the error in cmd:

Answer 1

Should be:

const translated = await translate.translateText(params.Item).promise();

See translateText where you see that it expects an object containing SourceLanguageCode, TargetLanguageCode and Text, just like the Item key in your params variable.
