Error: could not unmarshal the value dynamodb
What's Causing This Error
The DynamoDB unmarshal
function can only accept an object (with data the structure of DynamoDB). Therefore, if you try to pass an array of these objects into the unmarshal
function, it will throw an error.
Solution: Here's How To Resolve It
To resolve the error, iterate through the array of DynamoDB objects and "unmarshall" each object individually, as shown below.
const items = [ { uId: { S: '123456789' }, date: { S: '09-06-2022' } } ]; const unmarshalled = items.map((i) => aws.dynamodb.converter.unmarshall(i));
