Launching of recovery instance failed in failback process of AWS DRS

After completion of Reverse replication in case of Cross Region failback, launching of recovery instance failed with below mentioned error:

Error: An error occurred (VPCIdNotSpecified) when calling the RunInstances operation: No default VPC for this user. GroupName is only supported for EC2-Classic and default VPC.

How should I fix it?

You help is appreciated.
