Here you have a list of error codes based on trial & error, I couldn't find any official information about this: 

const errFileWritePermission = 0x809037D1;//2156935121

const errFileReadEmpty = 0x809037D2;      //2156935122

const errFileNotFound = 0x809037D5;       //2156935125

const errMediaNotPresent = 0x809037D8;    //2156935128

const errFileWriteEmptyStr = 0x809037D9;  //2156935129

const errDirExist = 0x809037DA;           //2156935130

 So in your case it seems to be a FileNotFound error.

Hello Everybody,

I've the same problem, TraceViewer report show me an errorcode = 2156935121.

The list posted above could help a lot, I'haven't been able to find any documentation regarding JavaScript errors. 

PLS, ro14, Mai I Know where did you find them? 

Many thanks

Hi,

from WinCC Unified V18 you can use the "GetDetailedErrorDescription" method to obtain a detailed error description of the error code.

Kind regards
