Error: dynamodb put item not working

Answered by Rafal Wilinski
What's Causing This Error
This error mainly occurs with the AWS JavaScript SDK when putItem()
function is used as a promise-based function.
For example, suppose you are executing the putItem()
in a Lambda function and do not wait until the execution is complete. The Lambda function will immediately return a response, but the putItem()
will not get executed.
Solution - Here's How To Resolve It
To resolve the error, use an async-await approach as shown below.
exports.handler = async (event) => { const obj = { pk: 1, name: "Lakindu" }; const response = { statusCode: 200, body: JSON.stringify(obj), }; var params = { 'TableName':'dynobase-article-demo', 'Item': { 'pk': { N: obj.pk }, 'name': { S: obj.name } }, 'ReturnConsumedCapacity': "TOTAL" }; // await for the put item so that it becomes synchronous. await dynamodb.putItem(params).promise(); return response; };
