After days of troubleshooting i found out the problem was because of the s3 bucket prefix list id which i forgot to mention, i still don't really understand why the prefix is needed tho.

here is the portion of code which helped me :

resource "aws_vpc_security_group_egress_rule" "fe_egress_s3" {
  description       = "Allow fe tasks to pull image layers from S3"
  security_group_id = aws_security_group.app_fe_sg.id
  from_port         = 443
  to_port           = 443
  ip_protocol       = "tcp"
  prefix_list_id = aws_vpc_endpoint.s3.prefix_list_id
}
