The below implementation is working with SpringBoot version 2.0.2.RELEASE.
After some dependencies upgrade the code fails to autowire DataRecordDBItemRepository.
The upgrades were:
spring-boot-dependencies 2.2.6.RELEASE
io.github.boostchicken:spring-data-dynamodb 5.2.5 (instead of com.github.derjust)
aws-java-sdk 1.11.807
jsk-bom 2.8.0
I also tried to add @Entity annotation but then I received multiple other errors.
As this implementation is working with older Spring version, I would like to understand why the upgrade in SpringBoot triggered the failure.

One of the pom.xml upgrades were
io.github.boostchicken:spring-data-dynamodb version 5.2.5
which replaced com.github.derjust:spring-data-dynamodb version 5.0.4
I had another dependency that also imported the com.github.derjust.
The impact was that I actually had dependencies to both io.github.boostchicken and com.github.derjust. Spring didn't know which lib to use for the required @Bean.
Excluding the com.github.derjust lib from the other dependency solved the issue.
