Error - Object reference not set to an instance of an object

[marci080]

Hi @KahPou_Liew

Are you using any Variables or Arguments in your Flowchart?
If you do, try providing initial/default values for them.
Basically, the NullReferenceException occurs when you access those variables that are NULL (= not set to an instance).

Your query is similar to this one so please check this for more hints

NullReferenceException at the start of the process

I am getting a NullReferenceException at the start of the process. “Object reference not set to an instance of an object. This error usually occurs when using a variable with no set value (not initialized).” It does not point to any activity. The error points to the start of the process. I am not sure if this explains the error clearly. Please let me know if any additional information is needed. Thanks in advance [image]

If the problem persists, we could help you more if you provide the xaml or screenshot of the logs/local pane.
