UiPath.UIAutomation.Activities v21.10.3 - strange problems after upgrading from 21.4.4

Hi @ripers

It looks similar to this one:

Bug Report - System.Activities.statements.Assign activity throws Cannot implicitly convert type 'object' to 'string'. An explicit conversion exists (are you missing a cast?)

Hi @sree_hari Our team looked into the issue and it comes down to a weird way this specific assign activity was coded in the XAML file. It points to an object while you are assigning a string: [image] [image] The quick and easy fix here is to: remove str_NewNumber from the assign activity save the workflow add str_NewNumber to the assign activity This is a workaround. As to the cause, we are not quite sure how to reproduce the root cause of the wrongly set variable type in the underlying…

Our team had a look at that previous one and was unable to find steps that would result in a faulty, underlying XAML code.

Before it started working again for you, have you maybe edited your file? Redoing the steps in the workflow file should normally fix this issue and would explain why it is working for you now.

Would you be able to still share a XAML file that is causing this issue (either here or privately via a PM to me @loginerror)?
