Cognos ( postgres ) connection failing SQL

I have a connection defined from Cognos Analytics to an Incorta instance 4.9  - the connection tests fine ( currently ) but when I try to pull data I get an error ( file attached ) 

--

Data source adapter error: org.postgresql.util.PSQLException: ERROR: Failed to get metadata  ( later in the file it give error when falling back to spark )

--

The ( an ) odd thing is that I *can* pull metadata ( "table" and column names ) but get this error when trying to query the data.  

Spark is running.

Any ideas on where to start with this?

  • adding - down the log file a bit I find this:

  • This would suggest a problem with your schema's data.  Are you able to build an Incorta dashboard against this schema successfully?

    • Dan Brock  Hi Dan - yes, it works fine in Incorta.  I have a case open ( 9900 ) w/ an INC filed:  INC-26960    

       

      We were able to get it working by disabling a system property on the server.
