6 months ago I was also experiencing this issue when running the image from: mcr.microsoft.com/azure-functions/dotnet-isolated:4-dotnet-isolated8.0
Exception was being thrown from the same place as in OP's stacktrace (HttpApiHandler.cs, GetWebhookUri method.)
return this.webhookUrlProvider?.Invoke() ?? throw new InvalidOperationException("Webhooks are not configured");
Following mention of this exception message in a previous issue HttpStart failure: Webhooks are not configured, I was able to workaround by adding the following Env variable to my container: WEBSITE_HOSTNAME=localhost:80 Which I guess isn't an acceptable workaround for a deployed container (?), but was sufficient in my case because the container was only being used for local integration testing.

Description
So I converted my Function App to be
"FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated",by following this article: https://learn.microsoft.com/en-us/azure/azure-functions/migrate-dotnet-to-isolated-model?tabs=net8It's running under kubernetes so my DockerFile uses the following image:
I can run the function app without problems when I run locally (using Rider IDE), and also when running in an Azure Function app, but when I run under Kubernetes I get the following exception: I want to point out that the function here is a cosmos trigger function that calls into an Orchestration (i.e. the DurableTask stuff in the ex) and it is failing somewhere in the DurableTask code.
Note that I was able to run my function app without issue prior to upgrading to isolated worker.
