Hi, I am getting the following errors when trying to query Jasper Studio using my custom JDBC driver created by calcite. Select portfolioCode from Portfolios Select `portfolioCode` from `Portfolios` Select `Portfolios`.`portfolioCode` from `Portfolios` All the above queries do not work. It failed when trying to create a dataset. The metadata is loading correctly, but when I try to generate my query, it failed at "Query execution error" When I just proceed with the error, there are no columns for me to select to add into the "Table" element. Attached Screenshot. 1) Is there a log in Jasper Studio where we can see what this error is about? Looking at metadata/.log, there is no error message 2) What could be the problem? Jaspersoft Studio 6.20.1
