Logic app blob trigger not fired on subfolder

Question

I am referring to this feedback:

Azure Storage Blob Trigger to fire when files added in Sub Folders

I have a Azure Logic App that is fired every time a blob is added in a container. This works fine when all the documents are at the root of the container.

Inside my container, I have a dynamic number of (virtual) sub-folders. When I add a new document in a subfolder (path = mysubfolder/mynewdocument.txt), the logic app is not triggered.

This does not really make sense for me as sub-folders in the blob container are virtual. Does anyone find a workaround except putting all the files at the root level ?

I've opened an issue on Github:

Answer 1

This is the expected behavior. None of the Logic App Triggers that work with 'files' support subfolders.

This has been the case with BizTalk Server as well since 2000 so I would not expect a change anytime soon :(.

I also can reproduce it on my side. I recommend that you could use the Azure function app blob trigger to instead of Azure Logic App blob trigger. Azure blob trigger function could be fired when you add a new document in a subfolder(virtual).
