AWS lambda - unable to invoke Lambda using AWS lambda connector

Hi all, I am facing an error while using InvokeFunction Java action of AWS Lambda connector module. I am not sure whether I am doing in a correct way or not. Below in detail We have one Lambda function URL . That will get a question as a input request and gives answer in a JSON format.   From postman , I am setting authorization as AWS signature , AccessKey , Secret access key, Service name, region  and I am getting the answer without any error.  Now I want to implement the same in Mendix using Lambda connector module. For InvokeFunction I need to pass Credentials, Region, InvokeFunctionRequest Objects.  1. For credentials, I am using Static credentials ( Calling Get Static Credentials microflow ) 2. Region , I using an enum that also present in AWS module 3. For InvokeFunctionRequest I am setting Function name : ABC Payload : { "query" :"What is ABC "} Invocation Type : AWSLambdaConnector.ENUM_InvocationType.REQUEST_RESPONSE The response I am getting is  : {"errorMessage": "'body'", "errorType": "KeyError", "requestId": "30654d4f-3a90-4a45-9ee1-076e7b0d7a81", "stackTrace": ["  File \"/var/task/\", line 6, in handler\n    print(f\"EVENT BODY: {event['body']}\")\n"]}{"errorMessage": "'body'", "errorType": "KeyError", "requestId": "30654d4f-3a90-4a45-9ee1-076e7b0d7a81", "stackTrace": ["  File \"/var/task/\", line 6, in handler\n    print(f\"EVENT BODY: {event['body']}\")\n"]}.   If anyone know what mistake i did or how to resolve my issue please help here.  Thanks.  See below screenshots for more understanding From Postman From Mendix

The error says "KeyError" so it must be the Function Name. I digged a little deeper and found that the Java call uses the Lambda ARN as the function name. See the screenshot below.
