Hi, Looking at your traceback, it doesn't look like it's calling your custom save() method. Do your current tracebacks show your custom save method?
You could try print(vars(self)) right before saving to see if there is a None that shouldn't be there. Again, if the traceback is happening in the browser, see if you can figure out what's in the "params" dict by clicking "local vars".
