Error within internal methods

Question

Hello,I have been receiving exceptions within some of the internal methods that syncfusion is using to build charts. One example is here: In this case, I'm assuming that something is not set correctly / is null. Is there a way to best troubleshoot these issues? And do you have any suggestions on what I may be missing in this specific case?Thank you,John

This is another example / an error that also comes up fairly frequently, again it is an error within an internal method. Are these methods reachable, or would you be able to provide any guidance on how to troubleshoot?

Thank you,

HeatMap issue

We are unable to reproduce the reported scenario in the
  HeatMap component. From the provided screenshot, we came to know that you
  have used the legend in HeatMap. So, we have created a simple Blazor
  application with the HeatMap component enabling legend and the same can be
  downloaded from the below link.

Hi Hemanathan,It's tricky for me to provide an accurate reproduction of what our codebase is, but I'll try. In the meantime I was thinking it would be easier if I knew exactly what parameters are needed for the above methods that are throwing the exceptions. That way I know where to best add null guards, as I assume the exceptions are being caused by inaccurate data on our part. Would information re: the parameters for the above methods be something that can be provided?Thank you,John

Hi John,Thank you for the update.To resolve reported exceptions, we can provide null
checking conditions in our component. It may not always solve your specific
problem. Please provide us with a code snippet that allows us to reproduce the
reported issues. It will assist us in determining the exact problem and
providing an appropriate solution. You can provide dummy data if the provided
data source contains any confidential information. You can also modify the
samples provided in our most recent update and send them to us in order for us
to reproduce the reported issue. Regards,Indumathi R.
