if we have Generic Variable called Description2 and we assigned the value like

Description2 = row(“Discripiton2”).ToString

after some time if we changed the Data Type of Description2 variable from Generic Value to String the following error is comming
Error : cannot assign from type ‘UiPath.Core.GenericValue’ to type ‘System.String’ in Assign Activity

anywhy we can solve by just remove the text from value box [row(“Discripiton2”).ToString ] and save the work flow and re enter the value it is solving , i think it s bug

Hi @sudheern,

If you are getting the error “Cannot assign from type ‘UiPath.Core.GenericValue’ to type ‘System.String’ in the Assign activity,” it means that you are trying to assign a value of type UiPath.Core.GenericValue to a variable of type string, which is not allowed.

One common cause of this error is trying to assign the output of an activity to a string variable without first converting the output to a string. For example, the following code would trigger this error:

Copy code

string myString;
myString = GetFullName.Output;

To fix this error, you need to convert the output of the GetFullName activity to a string before assigning it to the myString variable. You can do this using the ToString method:

Copy code

string myString;
myString = GetFullName.Output.ToString();

Alternatively, you can use the Assign activity with a type conversion:

Copy code

string myString;
Assign myString = (string)GetFullName.Output;
