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'

Please help me to setup this

No repository file or test is named; begin by reproducing GET /dev/hello with Serverless Offline and inspect the generated temporary path shown in the error. Done means the Java, DynamoDB, and API Gateway endpoint can be invoked locally without the EISDIR failure.
