RuntimeError

Running FastAPI in Debug mode reloadium shows an error.

Reloadium experienced a fatal error and has to quit.
Please submit a github issue to let us know at https://github.com/reloadware/reloadium

Process finished with exit code 1

Running in normal mode I get this error:

Without Reloadium the application runs fine. Any clue on how to solve this?

@Kompas I'm sorry for the late reply, I missed this (in the future please file issues in the Issue section).
Could you please provide which version of the plugin are you using?
Could you please run it with RW_DEBUG environmental variable set to Trueand run again?
