So we’re using the database connector to get data from an microsoft sql server. This work fines for most data retrievals but we have an error on 1 datacall (see below). We’re getting a null pointer exception but we’re not sure what is causing it. What’s special on this datacall is that the results have some NULL fields and maybe more importantly, there is one value field that containt values ranging from -2.0E+320 till 2.0E+320. Could this be giving an issue and if so is it possible to solve this? Kind regards error report: An error has occurred while handling the request.
