Stack Overflow Error when trying to search for a closed Task in Agent Workspace

[Jackie23]

Our Service Desk came across an issue when they were trying to access a closed REQ, specifically from Agent Workspace and Service Operations Workspace. When they opened the TASK it would open for about 5 seconds and then immediately error out. I have posted the error below. 

This is only happening in Agent Workspace and Service Operations Workspace, they can access the TASK just fine from the platform. As an admin I can recreate the issue and I am stumped. I have tried incognito, multiple different browsers, clearing cache. It only seems to be this specific catalog item and if it is closed. Any thoughts on where else I could look?

Thanks!

I'm not sure if you've already found a solution since this post is a few months old, but I want to share the solution I discovered for others who might encounter the same issue in the future.

In my case, I was using an MRVS along with some variables. The problem was that I had a start container named "start" in both the variables and the MRVS. The solution was to rename the start container in one of them to something else.

Note that this issue can occur if you have any two variables with the same name, not just the start container.
