Error running the OrchardCoreContrib.Modules.Web project

[DrewBrasher]

I forked this repo and cloned it to my machine and tried to run the OrchardCoreContrib.Modules.Web project but I'm getting errors. I think I must be missing something that needs to be in the appsettings file but I don't know what it would be.

The first time I try to run it after a fresh cloning I get the Object reference not set to an instance of an object. error in this screenshot in visual studio but I don't see anything that is null:

If I stop debugging and run it again I don't get that error again but the webpage shows this error:

Hi @DrewBrasher, I will try to reproduce the issue, because I didn't see such error previously

[hishamco]

@DrewBrasher I just tried to delete App_Data and started fresh, everything works as expected, please run git clean -xdf and try again

[DrewBrasher]

I tried git clean -xdf and get the same results as before. I also tried on another computer and got the same results.

[DrewBrasher]

If I disable hot reload, I can continue past the exception in visual studio and after continuing past several of those exceptions for other features the webpage will load and I can log in.

Then I can stop the app and run it again and the page loads now with no exceptions.

[hishamco]

Could you comment the code inside the InstalledAsync and then check

[DrewBrasher]

If I change it to this:

    public Task InstalledAsync(IFeatureInfo feature) => Task.CompletedTask;
    //public async Task InstalledAsync(IFeatureInfo feature)
    //    => await _migrationRunner.MigrateAsync(feature.Extension.Manifest.ModuleInfo.Id);

It runs fine with no exceptions.

[hishamco]

Strange!! The line above is used to install the features with custom migration

[DrewBrasher]

With that commented out, if I go to Tenants in the dashboard, and select the blog tenant I get this exception in the browser:

[hishamco]

Could you try building a new OC app and reference the modules that you want to try

[DrewBrasher]

The reason I was trying to run it from the source code is because I'm planning to add a new module for issue #101 .

[hishamco]

I'm still surprised why this happening, I already created all the available modules then added a reference to the module in the web app

[DrewBrasher]

Could you try building a new OC app and reference the modules that you want to try

I created a new OC app and referenced the IssueTracker module and that is working so I think I'm good to go as far as being able to work on that module.

[hishamco]

I will have a look into your PR, we can put a brief plan for this module as an initial version then we can extend it over the time

Thanks again

[hishamco]

The project works fine for me. I will close this, but feel free if this occurs again on the latest bits
