'VisualBasicValue '1' Compilation Error

[Srini84 (Srinivas)]

@makboga

Have you copied, paste the same Assign activity? If so It’s better to drag a new Assign activity and give the expression again

If this is not the case, then change the double quotes and that would be fine, below post for your reference

Assign: Expression Activity type 'VisualBasicValue`1' requires compilation in order to run. Please ensure that the workflow has been compiled

Hi @Gokul001 thanks for the answer, but when i tried to use in another project there is no error when i run. The error only appear when i use that project. dtFinal.AsEnumerable().Where(Function(a) String.IsNullOrEmpty(a.Field(Of String)(“Email”).ToString) ).CopyToDatatable(), this is my value in assign activity. What do u think about that, do u know how to resolve this problem?

Hope this may help you

Thanks
