Micronaut AWS Lambda and S3 Event - Guide Example Error

[mark-j-68]

Creating issue as requested in https://stackoverflow.com/questions/77781130/micronaut-aws-lambda-and-s3-event-guide-example-error. Original content copied below;

I downloaded the example project from the "MICRONAUT AWS LAMBDA AND S3 EVENT" guide and followed the instructions to create the Lamdba, the S3 Bucket, and put a Trigger on the S3 bucket.

However, whenever I drop a jpg file into the images folder in the S3 bucket I get this error in Cloudwatch.

An error occurred during JSON parsing: java.lang.RuntimeException

I had expected it to work as it's the example code from the guide and create thumbnail files.

My JAVA_HOME is set to "/home/mark/.jdks/corretto-17.0.9"

I only just noticed this - but my issue seems to be a duplicate of #1410.

I attempted similar workarounds with similar results.
