Issue Details

When I try to send cluster data type via shared variable, I receive error -1950678965. 


For cluster data type, a shared variable needs to refer to a custom control (.ctl file). The error usually occurs when the data type that the shared variable refers to does not exactly match the data type of cluster data that is to be sent. 
  • Check if the shared variable is referring to the right custom control. If not, right-click the shared variable in the project file, go to Properties and change the path of the custom control to the right one.  
  • Check if the custom control is set to type definition/strict type definition. If so, set Control Type to Custom Control.
  • Create a new custom control for the cluster data of interest, and let the shared variable refer to it.
