When building using make all, GetNodeInfo,hpp is not found

Hi, I encounter a similar problem. I can't find file NodeStatus.hpp. I find the same module libuavcan in PX4 repo Firmware and I can build it. So I believe the building environment is wrong.
I check the build output and find the python generator fail. I disable the conda environment and use python 2.7 to build, and it pass.
I think you should check the building environment according to PX4 Guide and use the same environment to build PX4-FLOW.
Good Luck!

@akvavit01 and @RPFey I think I solved it. The problem happens with the new versions of Python; I am using the 3.8.5 which comes with Ubuntu 20.04, here more information. Specifically, you need to handle the stopIteration exception version in /PX4-Flow/src/lib/uavcan/libuavcan/dsdl_compiler/libuavcan_dsdl_compiler/init.py since after Python 3.6 this will end up in an error. In this case, the error stops the generation process of some files such as Nodeinfo.hpp. Specifically, I modified the line 300 in init.py for handling the exception:
try:
last = next(it)
except StopIteration:
return

Excuse me for the identation, be careful with that since Python is very picky.
