unable to resolve class com.intellij.database.model.DasObjectWithSource

Hey guys,

we are currently testing DataGrip in our department, so that the toolbox can possibly replace our current tools.
I am currently testing the automatic generation of DDL files so that they can be included in our versioning system.

To do this I have selected the schema I want to use to generate the files, started the SQL Generator and went to the floppy disk on the left side. As layout I chose "File per object". But when I click on save, the following stacktrace appears:

File per object.groovy: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Script4.groovy: 1: unable to resolve class com.intellij.database.model.DasObjectWithSource

Script4.groovy: 2: unable to resolve class com.intellij.database.model.DasSchemaChild
@ line 2, column 1.

2 errors

It's a completely fresh installation of DataGrip v2019.3.4 Am I doing something wrong?
