Expected Behaviour
The example for core utilities with GraalVM works without throwing an error.
Current Behaviour
When I run the existing core-utilities example with sam-graalvm, the function errors with a function runtime error. See debug log below.
Code snippet
sam build --use-container --build-image powertools-examples-core-sam-graalvm
Possible Solution
It seems with the PR merge of #1927 this error occurs as the library has some changes with regards to the native libraries.
Steps to Reproduce
Run the examples/powertools-examples-core-utilities/sam-graalvm and notice the errors upon calling the rest api endpoint.
