Error: missing required key 'key' in params dynamodb

Answered by Rafal Wilinski
What's Causing This Error
This error occurs when the Key attribute has not been provided for the DynamoDB operation. For example, the GetItem or Get (in document client) uses the Key attribute to get the item for the given partition key.
Solution - Here's How To Resolve It
To resolve the error, navigate to the code that executes the DynamoDB operation and ensure that you've provided the Key parameter as shown below.
const doFunStuff = async () => {
const { Item } = await documentClient.get({
Key: {
pk: 'test'
},
TableName: 'test-table'
}).promise();
console.log('Item', Item);
};
doFunStuff();
