Error: DynamoDB FilterExpression Not Working

Answered by Rafal Wilinski
What's Causing This Error
This error can occur when you use FilterExpression on primary keys in DynamoDB query operations. If not, it can occur if there is no matching data to the filter criteria you specify in DynamoDB FilterExpressions.
Solution: Here's How To Resolve It
For DynamoDB query operations, check and confirm that you are not using FilterExpression on sort key or partition key attributes. If so, specify those key attributes in the key condition expression.
