Authorization header issue with Microsoft.ApplicationInsights.AspNetCore v2.1.0

I’m trying to setup a simple Blob storage backend following the guide here: https://docs.microsoft.com/en-us/azure/storage/vs-storage-aspnet5-getting-started-blobs

Here’s my current code:

cloudStorageAccount = CloudStorageAccount.Parse("UseDevelopmentStorage=true;DevelopmentStorageProxyUri=http://ipv4.fiddler");
blobClient = cloudStorageAccount.CreateCloudBlobClient();
blobContainer = blobClient.GetContainerReference("data");
            
await blobContainer.CreateIfNotExistsAsync(); // StorageException here

Here’s the request as captured by Fiddler:

PUT http://127.0.0.1:10000/devstoreaccount1/data?restype=container HTTP/1.1
Connection: Keep-Alive

I’ve been trying to look for a way to get the version of the string to sign used by the client library, but all the guides I’ve found are for .NET Framework (and not Core). (e.g. https://docs.microsoft.com/en-us/rest/api/storageservices/client-side-logging-with-the-.net-storage-client-library and “The TraceSource provider” at https://docs.microsoft.com/en-us/aspnet/core/fundamentals/logging#built-in-logging-providers)

Any ideas on what to try next? Is logging available on a .NET Core project?

@contactsamie Can you check applicationinsights.config file to verify that the following section exists? <Add Type="Microsoft.ApplicationInsights.DependencyCollector.DependencyTrackingTelemetryModule, Microsoft.AI.DependencyCollector"> <ExcludeComponentCorrelationHttpHeadersOnDomains> <Add>core.windows.net</Add> <Add>core.chinacloudapi.cn</Add> <Add>core.cloudapi.de</Add> <Add>core.usgovcloudapi.net</Add> </ExcludeComponentCorrelationHttpHeadersOnDomains> </Add>
