Using blobTrigger with Azurite crashes function host - azure

Question

I'm running into a problem with a Azure blob triggered function crashing the function host. It seems to be an issue with the storage connection string or how I'm using Azurite. Other timer or HTTP trigger functions I'm working on work fine with the "UseDevelopmentStorage=true" setting and the Azurite blob service running.
I'm rather stumped as to what the issue could be with getting a blob trigger function to work in my dev environment using the Azurite storage emulator.
Any suggests about what I'm missing or where to look futher?
This is the error message I get about 10 to 20 seconds after the function host starts:
An unhandled exception has occurred. Host is shutting down.
Microsoft.WindowsAzure.Storage: No connection could be made because the target machine actively refused it. System.Net.Http: No connection could be made because the target machine actively refused it. System.Private.CoreLib: No connection could be made because the target machine actively refused it.
The function.json file for the blob trigger function looks like this:
{
"scriptFile": "__init__.py",
"bindings": [
{
"name": "myblob",
"type": "blobTrigger",
"direction": "in",
"path": "outcontainer/{name}",
"connection": "AzureWebJobsStorage"
}
]
}
The local.settings.json file has this:
{
"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "python"
}
}
This is the output from console with the --verbose switch enabled:

Answer 1

Looks like I found what I was doing wrong. The documentation says, "The Azure Blob storage trigger requires a general-purpose storage account."
I was only starting the Azurite blob service. Starting the whole thing gets it working.

To run a Node blobTrigger locally you need to:
Make sure you are running Node 8 or 10. I run 10.14.1
Change local.settings.json:
"AzureWebJobsStorage": "UseDevelopmentStorage=true"
Run azurite with all services. Not only BlobStorage.
