When opening the dashboard portlet you get:
"This portlet has been undeployed. Please redeploy it or remove it from the page"
When trying to redeploy it's no longer available in UMP.
In the wasp log you will see:
Caused by: com.googlecode.flyway.core.api.FlywayException: Migration of schema `ca_uim` to version 1 failed! Please restore backups and roll back database and code! Thanks, Roberto
