That issue should have indeed been fixed in the latest version.

Hello,

Some months ago I reported a problem when returning null values from an embedded py function (may they be inside arrays or data frames). Indeed, the null values cannot be queried using sql like:

SELECT * FROM t WHERE v IS NULL

the above query does not return any result, but selecting the row mclient presents a ‘null’ values in the cell.

I am using a development build of a couple of months ago, I would like to know if this issue has been resolved or not.

Thank you
