DBeaver, SQLserver. java.sql.SQLException: Invalid mapping to BYTE

I'm trying to access data from SQLserver via Denodo (I think version 6), using latest Dbeaver (on Win7). I'm not an adminstrator so have no visibility of Denodo setup etc. nor the database itself. I'm getting warnings when viewing data from views of DB tables that have one or more BIT columns. (see error below). Is this error likely to be with Denodo setup, or with some DBeaver setting/incompatibility? Error as follows: org.jkiss.dbeaver.model.exec.DBCException: SQL Error: Invalid mapping to BYTE. at org.jkiss.dbeaver.model.impl.jdbc.data.handlers.JDBCAbstractValueHandler.fetchValueObject(JDBCAbstractValueHandler.java:55) at org.jkiss.dbeaver.ui.controls.resultset.ResultSetDataReceiver.fetchRow(ResultSetDataReceiver.java:118) at org.jkiss.dbeaver.model.impl.jdbc.struct.JDBCTable.readData(JDBCTable.java:204) at org.jkiss.dbeaver.ui.controls.resultset.ResultSetJobDataRead.lambda$0(ResultSetJobDataRead.java:93) at org.jkiss.dbeaver.model.DBUtils.tryExecuteRecover(DBUtils.java:1539) at org.jkiss.dbeaver.ui.controls.resultset.ResultSetJobDataRead.run(ResultSetJobDataRead.java:91) at org.jkiss.dbeaver.model.runtime.AbstractJob.run(AbstractJob.java:95) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:56) Caused by: java.sql.SQLException: Invalid mapping to BYTE. at com.denodo.vdb.jdbcdriver.conversion.ObjectRowConverter.convertByte(ObjectRowConverter.java:218) at com.denodo.vdb.jdbcdriver.VDBJDBCAsyncResultSet.getByte(VDBJDBCAsyncResultSet.java:632) at org.jkiss.dbeaver.model.impl.jdbc.exec.JDBCResultSetImpl.getByte(JDBCResultSetImpl.java:355) at org.jkiss.dbeaver.model.impl.jdbc.data.handlers.JDBCNumberValueHandler.fetchColumnValue(JDBCNumberValueHandler.java:131)

It was a Denodo issue. Fixed by adminstrators this morning. Many thanks!

May we ask how you solved this issue? We experience the same with DBeaver 6.1.2 (on Win10) - Denodo 7 - SQL Server 2016.
