Mysql Router not sending Write request to R/W instance

I am doing InnoDB Cluster Group Replication for the first time. I stuck at the last step Mysql Router. Mysql Router is configured with bootstrapping, But the main issue is MySQL router does not send the write request to the Primary R/W instance after failover. After failover primary become node instance and the Error says The MySQL server is running with the –super-read-only option so it cannot execute this statement

I am following this tutorial

Thanks in advance
