Hi there, I am running into problems when I am trying to initialize models from older runs. Here is an example with a run I created yesterday.

As you see it works perfectly fine.

However, when I am trying to initialize an older run (from 2016), I am getting this error:

This might be related to the issue I recently raised about initializing models from flows (#718).
Is there anything I am missing, or are the older runs simply not compatible with the initialize_model_from_run function?
