Data Transformation Filter - Null Value Issue

Wappler General Bugs
#1

Wappler Version : 4.0.2
Operating System : W10
Server Model: NodeJS
Database Type: Postgres

Expected behavior

I have a multi query which returns 1 row, and 5 columns. I need to output only 4 columns. 5th column is need just on SA level.
So I used Filter Columns step to filter out the 5th column.

The output expected here is the 4 other columns, with the same vaules as returned from the query.

Actual behavior

One column has null. That gets turned into {} when filtered.

Outputting the query returns null correctly, as shown in screenshot above. But filtered data is incorrect.

I can’t reproduce this, it outputs null correctly for me. You could delete the lib folder, then save your action file again which will copy the latest files back to your project. It is possible that you have some old file there that wasn’t updated.

Ok. Out of office for today. Will try to check and report tomorrow.
