Getting error while deploying stack through CF- "the target must have at least one listener that matches the target group port"

Hello Team,

I am facing below error while creating the stack through cloudforamtion. I have already verified the CF template and not able to find root cause of this error.

"If the target type is AB, the target must have at least one listener that matches the target group port for any specific port override"

Request you to please assist to fix this error. Below is my CF template:- AWSTemplateFormatVersion: "2010-09-09" Description: "Create ALB, ALB security group, target groups, listeners and listener rules" Parameters: VPC: Type: String Description: The vpc to launch the service Default: vpc-53b04a34
