Add To Collection: The property ‘Collection’ of ‘Add To Collection’ is not initialized

Hello all, I’ve run into an error with the Add to Collection activity as indicated by the title.

I have looked at other posts in UiPath Forum and tried to initialize the list my self but to no avail.

In the screenshot below, ‘coords’ is the list of integers that I use in Add to Collection and that I try to initialize before I add to it.

Any help is appreciated!


Can you share the following screenshot?

  • Property settings of the Add To Collection activity.
  • Local panel when it stops for the exception under Debug mode



Give a try on
new List(of Int32)
