Segmentation fault (core dumped)

Hi,

when i check the new instance state as below:
mysql-js> cluster.checkInstanceState('root@mysql-secondary1:3307')
Please provide the password for 'root@mysql-secondary1:3307':
Analyzing the instance replication state...

The instance 'mysql-secondary1:3307' is valid for the cluster.
The instance is new to Group Replication.

{
"reason": "new",
"state": "ok"
}


Next, i tried to add the instance into cluster.
mysql-js> cluster.addInstance('root@mysql-secondary1:3307')
A new instance will be added to the InnoDB cluster. Depending on the amount of
data on the cluster this might take from a few seconds to several hours.

Please provide the password for 'root@mysql-secondary1:3307':
Adding instance to the cluster ...

Segmentation fault (core dumped)

Any advise why this happened? How can i solve this?

mysql 5.7.17 (docker)
mysql-shell 1.0.8


Many thanks in advance
