Mashup loading error whenever reading from input infotable (SeriesClicked, SelectedData)

[Deon]

Hi all,

My mashup is completed and working, that is until I tried adding a new function.

Currently I have a service that provide data to the bar chart and have my seriesclicked and selecteddata binded to another barchart which works, it takes in the x and dataField of the first barchart. The problem occurs when I try reading the x and dataField of the chart in the same service that provide the data to the chart.

Now my Mashup have loading error only on the chart, and only when I try to read the x or dataField of the input infotable. Any advice is greatly appreciated!

Hello @Deon ,

Could you pls share the sample entities, if possible? Also, share the Application Logs to identify the errors.

Hello Bhawna!

Thank you for helping! Attached is the Application Logs. I am sorry, I am very new to PTC and not sure which entities should I share.

The error is occurring in the code of service script RetrieveProgress, line 1, where you try to access the property x of some input variable. It looks like that input variable was not set or has no value.

Beside fixing that you don't provide value, all the services you call directly from a mashup should have proper error handling, i.e. a try-catch block and/or validating of input parameters so you don't return exceptions to the mashup.
