Connections seem set but are not

[JavierGOrdonnez]

Long Story Short
Im pretty sure this is a duplicate, but couldnt find the existing case.

I keep finding the issue that I upload a .zip file, connect to a python runner, and the connection looks properly set (also when I look at the inputs of the runner). However, when running, those inputs are not there, and it fails. Going out to the dashboard and back in reveals that the connection had not really been set / saved.

This is a very annoying bug that makes changing code (which implies deleting the existing filepicker and reuploading the code) an unreliable operation.
