var ddb = new AWS.DynamoDB(apiVersion: '2012-08-10')
AWS.config.update(region: 'eu-west-1')
var docClient = new AWS.DynamoDB.DocumentClient()
 const params = 
 TableName: 'TC_QUESTIONS',
 Item: 
 'questionId' : S: '001',
 'questionText' : S: 'Richard Roe'
 
 

 var putItemPromise = docClient.put(params).promise()
 putItemPromise.then(function(data) 
 console.log("Added item:", JSON.stringify(data, null, 2));
 ).catch(function(err) 
 console.error("Unable to add item. Error JSON:", JSON.stringify(err, null, 2));
 );

 await putItemPromise

No error is returned. No success callback. When I use the wrong column name I get an error back from Dynamo. I've tried running the it locally and on lambda. It executes, and exits. No rows get added to the Table. What am I doing wrong?

Edit:
Here is my CF for the DynamoDB table:

QuestionsTable:
 Type: AWS::DynamoDB::Table
 Properties:
 TableName: 'TC_QUESTIONS'
 AttributeDefinitions:
 - AttributeName: questionId
 AttributeType: S
 - AttributeName: questionText
 AttributeType: S
 KeySchema:
 - AttributeName: questionId
 KeyType: HASH
 - AttributeName: questionText
 KeyType: RANGE
 ProvisionedThroughput: 
 ReadCapacityUnits: "5"
 WriteCapacityUnits: "5"

'use strict';
const AWS = require('aws-sdk');
const docClient = new AWS.DynamoDB.DocumentClient(region: 'eu-west-1');

exports.handler = async (event) => 

 const params = 
 TableName: 'TC_QUESTIONS',
 Item: 
 'questionId': '001',
 'questionText' : 'Richard Roe'
 
 

 try 
 await docClient.put(params).promise()
 catch (e) 
 console.log(e.message)
 
;

If your table exists and questionId is your partition key, the code above works.

I think you were mixing things up a little bit, because since you're using DocClient you don't need to specify DynamoDB's types anymore. And this was the problem on your code. Just specify the raw values (like I did above, passing the String itself) and it will work.
