Cannot serialise ttype=function 9.04

Huh, that's unusual... and a very unhelpful error. I actually don't understand what this error means or what could be causing it. The logs don't really mention anything, except showing me that I mistakenly attempt to add quality module technology without checking if quality module exists. But otherwise, I have no idea what pypostprocessing is doing that causes Reverse Factory to display this error.

Unfortunately, the verbose log doesn't help me in any way. All I see are a bunch of attempts by other mods to add ingredients and technology unlocks without checking if those exist, but nothing from my own mod. Even running pypostprocessing by itself with Reverse Factory causes the error, and it doesn't give me a line number or function name or anything else that might be useful in tracking down what the issue might be.

I've opened a discussion on their page here, which might eventually help me track down the problem, or might just result in being marked as an incompatibility from their side, if they can't help. I don't see this specific error message anywhere else on their discussion tab, so it must be something unique to this mod.

As I understand it, there will be no solution to this problem or what?

No new information has been revealed between then and now. Looking at their changelog, they seem to have much higher priorities with getting their mod fully functional, before they can really spend any time looking at mod compatibility.

If I don't know what it is that I need to fix, then I can't fix it.

So yes, there is currently no solution, until the py team has a chance to check what the issue might be. I could ping them again, since it's been about a month since their last response, but considering they are still regularly cranking out fixes, I really don't think I will get any response.
