ModelsBuilder on Umbraco v8.8

[IainMartin-Ayr]

I'm using ModelsBuilder in API mode with the ModelsMode set to Nothing. Build my models in VS using the Custom Tool option.

I upgraded the site to Umbraco V8.8.0 and ModelsBuilder throws the 401 Unauthorized error and doesn't build any models. Took the site back to v8.7.0 and it's fine.

Looks like there's something changed in V8.8.0 that's preventing MB from authorizing in the back end - the Tools -> Options -> Umbraco config file was not touched or changed at all during this time, apart to check that the details were correct.

Hey just to chip in on this one, I am on Umbraco 8.9 and have the same issue. using the new version of the visual studio tool as well.

[LachlannRattray]

An update from me, it turned out that I had a slightly older version of ModelsBuilder and ModelsBuilder API installed upgrading to 8.1.6 now lets me generate models

[IainMartin-Ayr]

@LachlannRattray - So are you downloading the source files from Tag 8.1.6 on GitHub and building it yourself?

[LachlannRattray]

@IainMartin-Ayr im not I realized looking through NuGet that even though i had upgraded to 8.9 from 8.6.3 (i think) Models builder was at version 8.1 after i upgraded to 8.1.6 models were being generated again. I do however have an issue where the models do not seem to be actually implementing the base properties for IPublishedContent. But I think that might be a different issue.

@LachlannRattray - okay, now I'm totally confused :-) I'm looking at my Manage Extension dialog in VS and ModelsBuilder Custom tool is showing as version 8.0.5 and it has automatic updates checked. But I did notice on GitHub there's a comment under the latest release that it;s not being automatically updated as it might break things.

It's ages since I last installed MB, tending just to copy the DLL and so on from other projects, set the connection paramters in Tools > Umbraco and change the web config to the correct settings for my MB use.

However, looking at Umbraco 8.9, it seems to be mostly external provider logins is the main update for this, and I'm not too worried about that, so I'll probably stick with 8.7 for now as I know it's working in the way I want and am used to.

Hate VS and NuGet and GitHub and DLL hell sometimes........

@IainMartin-Ayr try to switch from the deprecated "custom tool" extension to the new Umbraco ModelsBuilder Extension. It is version 8.1.5 and for our team works fine with 8.8.0.

I also had issues on Umbraco.CMS 8.9.0 and Umbraco.ModelsBuilder 8.1.0.

The log in the General tab of VS said:
UmbracoModelsBuilder: Starting v8.1.5 17/11/2020 10:38:57.
UmbracoModelsBuilder: UmbracoModelsBuilder failed to generate code: Exception: Response status code does not indicate success (Unauthorized)

Then I've updated Umbraco.ModelsBuilder to 8.1.6 and everything started working well again.

I was getting the same "Unauthorised" issue after upgrading from Umbraco v8.7.0 to Umbraco v8.8.0. But I fixed it by updating Umbraco.ModelsBuilder, Umbraco.ModelsBuilder.API and Umbraco.ModelsBuilder.UI to v8.1.6 (from v8.1.0).

Same issue with recent upgrade to Umbraco 8.6.0 -> 8.9.1
Can confirm upgrade of Umbraco.ModelsBuilder and Umbraco.ModelsBuilder.API packages from 8.1.0 -> 8.1.6 fixed the "Unauthorised" error.
I then encountered an InternalServerError when generating the models which I think was due to us having customised some of the generated models. Moving the location of the .mb file that gets used by the Umbraco Models Builder Extension for Visual Studio resolved the issue.

I'm having these issues today on Umbraco 8.13.0 sites (some running on Umbraco Cloud). The NuGet packages are all 8.1.6, the VS extension is 8.1.5
