Hey guys, I am getting the following error in developer mode,
AttributeError: 'NoneType' object has no attribute 'label'
I have check my DocType, like a thousand times, and I have labell to all my Fields except the column breaks.
I even bench migrate thinking that it might be some older version of the DocType because my next logical assumption is that somewhere a Field I created and deleted, is kept.
Goes make sense to anyone? Anyone knows any tip or trick to debug this problem ?

Right now I am trying to debug in frappe/model/meta.py
@kickapoo, Might be label is missing in one of your fields. Refer following attachment -
Regards, Priya
Might be that you are using “name” as a field name which in my case sometimes created conflicts.
Frappe uses “name” in the DB instead of standard primary/foreign keys solution.
I would go for deleting doctype directories, removing doctype from GUI and then going for bench migrate.
Afterwards recreating doc.
@priya_s, Ty for answer but as I wrote, I have check my DocType, like a thousand times, and I have labels to all my Fields except the column breaks.
@Marcin_Walkow, I was suspecting the “name” issue and had already check. It not the case.
Deleting the DocType, I dont find this good idea because let’s think of the scenario that this error occurs then you make a change to huge production doctype.
Right now you are developing & testing so let us spot the issue. Do not be concerned about the universal solutions for the future, focus on the ball 
For example I was trying to create doctype which contained name “Customer” and was unable to do so. After removing directories and cleaning stuff it worked.
For me it looks like there is a field in some place (in some list) which existed but right now it does not / or the labels were not set for particular fields. I would go to meta.py
And in function:
def get_label(self, fieldname): return self.get_field(fieldname).label
def get_label(self, fieldname): print(fieldname) return self.get_field(fieldname).label
Not sure if print is gonna work (didn’t try it here yet), but when you have console up and running you should see each fieldname printed out.
@Marcin_Walkow, print didn’t work. Tried also to pass 'ipdb.set_trace()`
I will continue to search it…
@Marcin_Walkow and @priya_s, ty for your suggestions.
The solution was in front on me all the time,
the link @priya_s shared had it. The problem was that I had autoname using the deleted one
So for others:
Check your autofield settings in the DocType not to have ant deleted field name as input
Currently I am gathering some of the topics to work on the documentation - this is one of them.
Great it’s finally resolved.
