Edit: after checking how ...Http.AspNetCore returns errors for how HttpRequestData.Url is handled (it has thrown a UriFormatException), I found that the currently latest commit (Azure/azure-functions-dotnet-worker@bf56b37) might attempting to solve this issue.
We have also been dealing with the what could be the same problem for 2 days now. When going to "http://localhost:{port}/api/swagger.json" or "/api/swagger/ui" we get the error message below. It states One or more errors occurred. (Invalid URI: The URI is empty.).
Our best guess is that it's due to ConfigureAspNetCoreIntegration in https://github.com/Azure/azure-functions-dotnet-worker/blob/main/extensions/Worker.Extensions.Http.AspNetCore/src/FunctionsHostBuilderExtensions.cs
Here it's stated webBuilder.UseUrls(HttpUriProvider.HttpUriString); and HttpUriProvider is implemented as a string backed by a Lazy Uri in https://github.com/Azure/azure-functions-dotnet-worker/blob/main/extensions/Worker.Extensions.Http.AspNetCore/src/HttpUriProvider.cs
But we actually do not know what Uri is supposed to be read at Microsoft.Azure.Functions.Worker.Extensions.OpenApi.HttpRequestObject..ctor. https://github.com/Azure/azure-functions-openapi-extension/blob/main/src/Microsoft.Azure.Functions.Worker.Extensions.OpenApi/HttpRequestObject.cs
The open api generation actually works fine if I don't use ConfigureFunctionsWebApplication and instead uses ConfigureFunctionsWorkerDefaults but this contradicts with what is stated here: https://learn.microsoft.com/en-us/azure/azure-functions/dotnet-isolated-process-guide#aspnet-core-integration
