Ok found the problem, it happens if you use aliases in your queries.
Unpack the following dbConnector_rules.js
dbConnector_rules.zip (4.5 KB)
on Windows in:
C:\Users\username\AppData\Roaming\Wappler\Configuration\Shared\DMXzone\dmxServerConnect\rules
on Mac in:
~/Library/Application Support/Wappler/Configuration/Shared/DMXzone/dmxServerConnect/rules
Make sure you place just the js file there not the whole zip!
Let me know if it works
It will be included with the next update
