System error during load queue: Attempted to access an element as a type incompatible with the array

I’m recieving the following error when trying to load the queue.

“System error during load queue: Attempted to access an element as a type incompatible with the array.”

I have checked some other posts and tried to resolve the issue by changing the System.Activities package (tried both downgrading and upgrading) however there is still no difference.

The issue is only occuring while trying to load the queue in production, not in dev or while debugging.

Any help is appreciated!

How did you update the queue?
This error may occur when there is a different type of variables in the array. For example, in a string of an array, if there is an integer value, the error may occur.

Using a DT to string, the values are fine and working in all tests and in the Dev enviroment. Its only an issue in Production…
