Error while connecting to the MariadDB maxscale with tx

Question

While I tried connecting my Mariadb TX server using mxs_adapter and cdc connectors I get the following error:

2018-09-20 16:12:38 [cdc_test.cdc_tab] MaxScale connection could not be 
created: Exception caught: basic_string::_S_create

How can I resolve this?

Looks like you've hit a bug. The best way to solve it is to report it on the MariaDB Jira. Add the output you added here and explain what you were trying to do. It's more than likely that it will get fixed in the next release.

Meanwhile, you can try the cdc.py client that is packaged with MaxScale to verify that your MaxScale CDC setup is working.
