Error: could not unconvert attribute dynamodb
What's Causing This Error
This error occurs in Java when the mapper class is not defined correctly. For example, the SDK creates an instance of the mapper class using a "No-Arg" constructor and uses "Setter" methods to assign data to the object. So, you will run into this error if the mapper class is missing a No-Arg constructor or has invalid Setters/Getters that do not comply with the camel case convention.
Solution - Here's How To Resolve It
To resolve the error, ensure that you have provided a No-Arg constructor. This can be done by manually defining the constructor in your class or using a Lombok library.
Then, ensure that the getter/setter methods are correctly defined in the class. For example, if a mapper class has a property "age" of type Integer, the setter/getter would be similar to the snippet shown below.
private int age; public void setAge(int age) { this.age = age; } public int getAge(){ return age; }
