I feel like I am missing some configuration or something, because I have followed tons of tutorials online, but cannot get any examples of a script task to work. I cannot debug the error either because I am not a C# developer.
Currently, I am simply checking if a file exists in a directory:
User::gvLastMonthImportFile
is string (read-only) &User::gvLastMonthImportFileExists
is Boolean (read-write)Added
using System.IO;
to my namespaces
string fullPath = Dts.Variables["User::gvLastMonthImportFile"].Value.ToString();
Dts.Variables["User::gvLastMonthImportFileExists"].Value = File.Exists(fullPath);
Dts.TaskResult = (int)ScriptResults.Success;`

I ran into this recently and it was because I had not added the variables to the script.
You have to explicitly add ReadOnlyVariables/ReadWriteVariables to the script task for it to have any access to them by double-clicking the script task in the designer, selecting 'Script' on the right-hand side of the dialog and then clicking the ReadOnlyVariables/ReadWriteVariables drop down.
I know this reply is late but this caused me a lot of grief and hopefully it helps someone.

I had a similar problem, but I want to had a screenshot to help debug these cases : After closing the cryptic error prompt, watch into your debug output, there will be a short yet more useful error message :

I had that same problem and was stuck for a couple of hours. Then I found my problem. Variables are case-sensitive and I had misspelled one of them.
