Well, this is weird. The App works depending on the Query!
If I run a simple query getting 3 values, assigning one of them (NUM2) to a variable TREAD, it works:
Result:
Now, if I use my query, which returns a row using the same column names as above, not changing anything else on the App, it doesn't work!:
Result:
And it is evident that the variable value is correctly assigned.
Here is the new App;

I don't understand why changing the query to one that gives similar results (a row with same column names) would make the App (specifically the "Test variable1" action) fail?
