VSW debug mode warning details?

Hi,

When we start a VSW app in debug mode, there is a Warning in the console:
 

Note: this warning only appears with the Prod version of the app (different data schemes, perhaps). But what's puzzling us more is that the warning doesn't clarify in which layer this ‘Field does not exists..’ is detected. This makes the warning rather pointless. Is anyone familiar with this warning and where it can originate? Would it be possible to have more details when it comes to these warnings?

BR,
SIGGIS
