Hi Everyone, not sure of this is still an issue for others but I found my problem resolution was a little different to other posted. I had made a mistake in my inherited Document Types which caused my issue. I found the root cause by going to the folder [MyProject]App_Data > Models > and inside there was a file called models.err. This file gave me this error info:
Failed to build PureLive models.
Cannot generate model for type 'hero' because it is an element type, but it is composed of 'contentBase' which is not.

I simply fixed my Document Types and all good. I raise this as most other solutions were DLL or Nuget package based and this problem was much simpler. My errors and symptoms were identical but resolution completely different. I hope this helps someone who may be seeing something similar.
Nested content "Object reference not set to an instance of an object."
Hi! I've started to get this error on a fresh installation on Umbraco 8.3:

Can anyone help with this? If you need more info please tell me
Thanks in advance!
In addition Model.Value("grid") also returns null - seems like there's a bug with retrieving the data?
Hi, I have the same issue. Did you find any solution for it Christian?
hi Christian here is my fix
Install Umbraco.ModelsBuilder from Nuget In web.config you should have next values for Umbraco.ModelsBuilder

Thanks,
Thank @Danny, I have the same problem like you. I remove composition from base document type and it works normally.
Thanks, Phong. Spent ages trying to fix this and by removing the composition, it worked for me as well.
is working on a reply...
