Why do I get an KeyError when using Modules?

Hello,
I am currently working on a project on Determining Winners and Update them (they are vectors) . I implemented these function as seperate compiler to test their functionality and it works like a charm. But unfortunately this isn’t really my attended use case. I want it to work without an decryption and encryption step between the defiend circuits. So I tried using them as one big circuit and implemented in a module. I copy pasted my functions and inputset but on both approaches (one big circuit and module) I get the same Error of the following form:
KeyError: <concrete.fhe.representation.node.Node object at 0x7f473988d790>

How do I fix this error? Or are their other approaches to work without extra decryption and encrytion?
I would also pleased to know about what changes in the way the compiler works in the background, would be really interesting.

Best regards

Hello. To help you, we would need you to create a GitHub repository reproducing the problem, and you to tell us what command line to launch. Without a way to reproduce, we can barely help you. Thanks
