Studio project run fails with 'Too many arguments are problematic'

The Studio project fails with error BC32043 Too many type arguments. It fails at the "Add data row" activity, when an array is entered in the "ArrayRow" field.

When using Studio 22.10.8 with the System.Activities package version 23.4.x, it can happen that the “Add data row” activity will fail with the BC32043 error.


Resolution:
  • Upgrade UiPath Studio to v23.4 or higher (meaning, the latest Enterprise version available at the time of reading this article).
