SSIS Script Task throwing exception: The type initializer for 'PerTypeValues'1'

James Clark 231

I have a C# Script Task that's throwing an exception "The type initializer for 'PerTypeValues'1" running on the server. My package runs fine within Visual Studio. What the heck does this mean?

Hi @James Clark , sorry about that I don't familiar with C#. But after researched, this error may occurred when the script have something wrong. Please refer to this thread:

Check the InnerException property of the TypeInitializationException; it is likely to contain information about the underlying problem, and exactly where it occurred.

This action helped me to uncover another missing assembly: System.Runtime.CompilerServices.Unsafe, which was a different version of the same assembly already added to the GAC. Once I added both versions to the GAC, my problem was solved.

This error occurs while running my package on the SSIS server and it runs fine on my development computer in Visual Studio. I'm not able to install Visual Studio on the SSIS server, it exists in a data center and I do not have administrative rights.

I should have been specific, I'm using Visual Studio Enterprise 2019, version 16.10.0.
