Odd behavior using IF in ECL

I tried to run this code:
{{}}

dstcluster := IF(__CONTAINERIZED__, 'dstcluster=data ','dstcluster=mythor '); 
OUTPUT(dstcluster);

1. It passes the syntax check in IDE, but fails the syntax check in VSCODE. 
{{2. In IDE, if I submit it fails and says: Query is Empty. }}
   In VScode, it says 0003:  Definition must contain EXPORT or SHARED value for testENV_VAR-614779
