Modify Text Activity Error

Started getting the below error after upgrading the UiPath.Systems.Activity package to 23.10.6. Its failing at the Modify Text activity. Any recommendations on fixing the error. I wonder if the Transaction item it is referencing is the issue because the transaction item is being created using older dependencies (22.10.6) Thoughts? After downgrading back to System.Activities 22.10.6 the error cleared.

A workflow snippet shows an Assign activity for setting a variable, followed by a Multiple Assign activity for extracting and manipulating file path values, and a Modify Text activity circled in blue for modifying the variable through text replacement and trimming. (Captioned by AI)

@PWilliams

Try to recreate the variables again and check…that should sort…as the versions you are upgrading have mahor library upgrades around view models
