UmbracoModelsBuilder: UmbracoModelsBuilder failed to generate code: NullReferenceException
Opened this issue · 1 comments
Hi all,
We've encountered a problem with one of our repos wherein the Modelbuilder custom tool is no longer working and throws an error within which the exception message states 'Object reference not set to an instance of an object'. It seems to be the same as the closed issue encountered here: #160 (was unsure whether to post in a closed issue or open a new one; apologies if the former is preferred).
We have <add key="Umbraco.ModelsBuilder.LanguageVersion" value="CSharp6" />` within our web.config from prior to this bug (as per one user's recommendation on the #160 issue) and our Umbraco version is 7.13.1. Any information on things to try or what the possible underlying cause could be would be appreciated.
This is the full output for the error:

( As this issue is quite old - I'll create a new linked issue.. #259 )
I have the same issue - Umbraco 8.13.1 - added the web.config line etc.
If we do anything in the backoffice with doctypes etc, We get stackoverflow after the old generated models has been deleted, and before the new is generated.
After this the site will not start - Only solution to get the site restarted is to undo the deletion of the models (GIT undo changes).
Actual exception is in System.Collections.Generic.Dictionary.FindEntry() where key is IListableContent.
I've checked for looping compositions - any other ideas?
