Blob Storage upload (SFTP Preview) event not firing when using WinSCP to upload but working with Azure Storage Explorer

I am currently putting together a POC for the new SSH File Transfer Protocol (SFTP) feature in Azure Blob Storage.

I have hooked it up with an Azure Function so that when a blob is uploaded (created) or deleted then the Azure Function gets fired. This works fine when you upload a file from Azure Storage Explorer but doesn't work when I upload using WinSCP

Any ideas as to why?

    Hi John,

    Based on the storage documentation I don't think it's supported, see table below.

    I tried something similar (Event Grid triggered Azure function running locally) and had the same results, works when uploading via the Azure portal, doesn't work via sFTP via FileZilla.

    I also tried a blob Blob triggered Azure function and that function triggered as expected. Blob trigger probably works a bit differently (polling) and seems less reliable based on the docs.
