I'm prototyping a solution and I'm prototyping a solution and I'm confused about I'm currently developing an Azure Function in C# that reads data from a blob storage container, but I'm working with an scenario during the binding process. My function is not able to bind to the Azure Blob Storage, and I'm receiving the behavior message: `"Unable to bind to Blob Storage. Invalid SAS token"`. My Azure Function is set to use a Storage account connection string with a SAS token embedded in it. Here’s a snippet of my function code: ```csharp [FunctionName("BlobTriggerFunction")] public static void Run([BlobTrigger("mycontainer/{name}", Connection = "AzureWebJobsStorage")] Stream myBlob, string name, ILogger log) { log.LogInformation($"Blob trigger function processed blob Name:{name} Size: {myBlob.Length} Bytes"); } ``` In my local.settings.json, I have the connection string defined like this: ```json { "IsEncrypted": false, "Values": { "AzureWebJobsStorage": "DefaultEndpointsProtocol=https;AccountName=myaccount;AccountKey=mykey;EndpointSuffix=core.windows.net;SharedAccessSignature=..." } } ``` I've double-checked the SAS token permissions and made sure that it has read access to the blob container. The token is generated with an expiry time and limited permissions, so I should be compliant with the required access. I've also tried regenerating the SAS token and updating the connection string, but I still encounter the same behavior. Is there a specific format or configuration I might be overlooking when using SAS tokens with Azure Functions? Any insights or troubleshooting steps would be greatly appreciated! This issue appeared after updating to C# stable. I'm developing on Windows 11 with C#. What's the best practice here? I'm coming from a different tech stack and learning C#. Am I missing something obvious?
