"Failed to create DesignObjectSchema" errors appear in application server logs. Although the data server may start and run, the application server on all separate nodes in the high availability set up will fail to start successfully.
This error can appear when the dataserver.password property is inconsistent between all nodes.
Ensure that the data servers are able to communicate with one another. This can be done by reviewing the steps in the following documentation:https://docs.appian.com/suite/help/19.4/Data_Server_Connection_Restrictions.html
Specifically, ensure that the dataserver.password property within the data-server-sec.properties file is consistent across all distributed nodes.
