I have thousands of these exceptions in my logs and I would like to remedy them. But, I am not sure how to track this guy down. Any pointers?

There’s not a great way to do this, but you could use the Designer’s Find/Replace tool to search for “system.util.invokeAsynchronous” to determine where you’ve used that. That stacktrace seems to be missing a clarification as to what line of the script is using `system.util.invokeAsynchronous`; your Gateway logs might have a bit more info than what you posted, but this is where I’d start. Obviously newer scripts are more likely, but it could also be older scripts if you removed a project-level script they referenced.
