The console crashes after an attempt to create an instance with an invalid Database Suffix, because dscreate returns not just a JSON error, but also plain text during the installation.

1. Create a new instance and use `dc=test > /tmp/test` as a Database Suffix
2.
3.

`dc=test > /tmp/test` passes input validation as a Valid DN, while it's not. Later dscreate crashes with both plain text error and JSON error. But the plain text error confuses WebUI
