Dependency Injection Error in Production, but not Dev??

[Dmo16]

Hello gang,

I'm attempting to push my API to a production app service slot, and this exception gets thrown when attempting any queries:

Unexpected Execution Error
   at Microsoft.Extensions.DependencyInjection.ServiceCollectionExtensions.<>c.<AddGremlinq>b__1_1(IServiceProvider c) in /_/src/ExRam.Gremlinq.Core.AspNet/ServiceCollectionExtensions.cs:line 39

The rest of the stack trace:

To re-iterate, dev environment and integration testing work flawlessly, this only occurs on Azure App service.

Although it could be a lot of things, I'm asking here in case someone else has run into this.

Here's the method:

 public static IServiceCollection AddGremlinq(this IServiceCollection serviceCollection, Action<GremlinqSetup> configuration)
        {
            serviceCollection
                .AddSingleton<IGremlinqConfiguration>(serviceProvider => new GremlinqConfiguration(serviceProvider.GetRequiredService<IConfiguration>().GetSection("Gremlinq")))
                .AddSingleton<IGremlinQueryEnvironmentTransformation, UseLoggerGremlinQueryEnvironmentTransformation>()
                .AddSingleton(c =>
                {
                    var transformations = c.GetRequiredService<IEnumerable<IGremlinQueryEnvironmentTransformation>>();

                    return g
                        .ConfigureEnvironment(env =>
                        {
                            foreach (var transformation in transformations)
                            {
                                env = transformation.Transform(env);
                            }

                            return env;
                        });
                });

            configuration(new GremlinqSetup(serviceCollection));

            return serviceCollection;
        }

And then the chunk that starts at line 39:

return g
                        .ConfigureEnvironment(env =>
                        {
                            foreach (var transformation in transformations)
                            {
                                env = transformation.Transform(env);
                            }

                            return env;
                        });

I'm looking into it now. Would still very much appreciate a tip as to how to fix this, but if I find the solve I shall report back.
