Get Customer Input block throws error when using Lex as customer input

I am trying to configure lex bot in AWS Connect. I have created a demo Lex bot that is working fine in Lex but after integrating it with Aws Connect in the Get Customer Input block in the contact flow, it throws an error. I have checked the error in CloudWatch and you can see the error following:

{ "Results": "Error", "ContactId": "contactId", "ContactFlowId": "COntactFlowId", "ContactFlowName": "TalkToOctaveAgent2", "ContactFlowModuleType": "GetUserInput", "Timestamp": "2022-03-25T05:30:08.252Z" } I can't recognize where this error comes from. I have set lex intents in the Get Customer Input block with proper names as in Lex. Please let me know how I can resolve this error.
