I can, but it has a ton of custom dependencies. It's a graph I've been working on for months, so it has become a bit cumbersome. I'm not sure it would do any good to send it by itself? Let me know if you still want to look at it.
If anyone can just help me understand what that error means (ERROR_UNKNOWN_INSTANCE_PARAMETER_NAME), I can probably figure out the problem. Google didn't turn up much. I wasn't sure if it meant I had an exposed variable with no usage, or a usage with no variable, or something else entirely. The names of these two variables definitely sound familiar, so I'm sure it is something I changed and didn't complete properly.
If I expose the variable of a sub-graph, and then expose/attach that to a parent graph variable, then later delete the sub-graph variable entirely, will this cause any issues for the parent graph? I'm pretty sure I did this a few times. When I went to clean up the parent graph, it appeared to already be correct. But I wondered if it created some type of ghost bug.
