TypeError: Cannot call method "ServiceName" of null

TypeError: Cannot call method "ServiceName" of null

In a Thing, Made an Service Testing2, In this calling a Service(AddAlertEntry) from DataTable, when this is executed normally/Individually works fine.

When the same service(Testing2) is called from an subscription for every 15mins gives the following error:

 

 

Error in: Test_Thing.Testing2 javascript service. Message ::TypeError: Cannot call method "AddAlertEntry" of null (Testing2#1)

 

 

AddAlertEntry Code:

 

 

logger.warn(Code+ " " + Asset+ " " + Time+ " " + Alerts+ " " + Priority+ " " + Status+ " " + AlertDuration+ " " + UserInformation+ " " + Resolved);

var values = me.CreateValues();
values.Code = Code;
values.Asset = Asset;
values.Time =Time;
values.Alerts = Alerts;
values.Priority = Priority;
values.Status = Status;
values.AlertDuration = AlertDuration;
values.UserInformation = "Shashi";
values.Resolved = me.GetMaxID()+1;
var params = {
    values: values,
};
var result = Things["ActiveAlert_DataTable"].AddDataTableEntry(params);

Hi,

Found the issue, it is because no proper permissions were not given to the DataTable that was used in the Code, When permissions given, it got fixed.

Hi @Shashi_Preetham 

 

Can you enable Debug level logging and share the error you are getting in Script logs?

Goto subsystem>>loggingsubsystem>>Configuration>> check enable Stacktracing and try to reproduce the scenario.

You can also add loggers to find the point of failure.
