Errors when using R SWAT in SAS Viya 3.4

[Rain]

Hello

I have been following examples from book "SAS Viya: The R Perspective". I am facing some issues when executing code. Maybe someone can help me out, maybe the syntax or parameters have changed since the release of this book.

Using cas.table.columnInfo(cars) works correctly but cas.table.tableInfo(cars) gives an error:

Secondly, loading regression actionset: 

cas.builtins.loadActionSet(conn, 'regression') gives also an error:

When I use instead loadActionSet(conn, 'regression') I'll get another kind of error:

For comparison, then loading decision tree action set works just fine: 

loadActionSet(conn, 'decisiontree')

Finally, in order to get rid of CAS table groupby functionality I should use quotes like this: cars@groupby<-  ''

but this gives me an error when trying to calculate new summary:

@Rain ,

Please repeat the problem and show me the most recent CAS server log files from /opt/sas/viya/config/var/log/cas/default directory (from all CAS nodes).

Hi @alexal.

This is what I got from Viya logs not much. Basically the same messages as previously:
