Plugging the Python script inside of Uipath (RPA Software)

Working as a developer with a brand new software for automation of business processes that relies on the logic and functions of .net, I come across many problems that are more or less solved easily and with not that much effort - especially because there is a lot of documentation available. But once I had a problem that could not be solved with the Uipath, so I had to resort to implementation with a Python code that I was going to plug into the Uipah afterwards. I kept getting the Json Serialization Exception and even though the pyhton code was completely correct Uipath still didn't recognize it. When I went to forum I saw that I was not the only one having the problem.
