Error: dynamodb could not instantiate class
Answered by Rafal Wilinski
What's Causing This Error
This is an error that occurs when using DynamoDB in Java. For instance, you may run into this error:
- If you define a table class (class with the annotation
@DynamoDBTable(tableName=""))as a subclass of another class. - If it is defined within the same file as another class.
- If you have not defined getters/setters or a no-arg constructor.
Solution: Here's How To Resolve It
To solve this error:
- Ensure that you define your Java DynamoDB table classes in their separate file.
- Ensure that your class has a no-arg constructor.
