unable to test java application in serverless offline

Hi All
I have created a server less application using java,dynamodb and API gatway. i want to test this functionality in local using serverless offline framework. But i am facing the following issue while invoking the API. Please help me to resolve this issue.
offline: Starting Offline: dev/eu-west-1.
┌─────────────────────────────────────────────────────────────────────────┐
│ │
│ GET | http://localhost:3000/dev/hello │
│ │
└─────────────────────────────────────────────────────────────────────────┘enter code here
offline: GET /dev/hello (λ: hello)
offline: Failure: EISDIR: illegal operation on a directory, open 'C:\Users\saswat\AppData\Local\Temp\serverless-offline\services\example\hello\ckivvmja30
00254ty13fi3ks1\code\com\serverless'
Error: EISDIR: illegal operation on a directory, open 'C:\Users\saswat\AppData\Local\Temp\serverless-offline\services\example\hello\ckivvmja3000254ty13fi
3ks1\code\com\serverless'

The report mentions a Java serverless application, the GET /dev/hello entry point, and a Windows serverless-offline temporary path, but names no repository file or test. Start by locating the Java example and its offline configuration, then reproduce the request on Windows. Done means the endpoint runs locally without the reported EISDIR failure.
