'NoneType' object has no attribute 'id'

[Marcel Zwiers]

I got this error when running my network (see below). I'm not sure whether this is due to an error in my own code (probably yes) or that it is a bug in fastr or something else. I don't know how to debug this or how proceed from here, any suggestions? The logs or tmp directories don't provide much information (to me at least). Is there some debug documentation/guidance somewhere?

Seems it cannot find the resulting_datatype, this is most likely because a preferred datatype was not set somewhere and there are multiple options, but I am a bit curious why this doesn't give an error anymore (seems rather unsafe that it gives a way more random error doesn't it?) I will look into it further tomorrow afternoon or Monday.
