azure-storage-net-data-movement: AzCopy 7.0.0 breaks uploading into local emulated blob storage

Hey there, I hope this is the right place for my issue.

I’m using AzCopy 6.3.0 to upload folder contents to my local emulated blob storage (with Azure Storage Emulator 5.2) using AzCopy /S /Y /Source:folder /DestType:blob /Dest:http://127.0.0.1:10000/devstoreaccount1/mycontainer/Folder-Local /DestKey:Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==

When using AzCopy 7.0.0 which is now available under http://aka.ms/downloadazcopy (is there a public repo btw?) this does not work anymore. It throws an error like

Error parsing destination location “http://127.0.0.1:10000/devstoreaccount1/mycontainer/Folder-Local”: Transfer from a directory to a file is not supported. (Attempt to parse address ‘http://127.0.0.1:10000/devstoreaccount1/mycontainer/Folder-Local’ to a directory location failed: Cannot find account information inside Uri ‘http://127.0.0.1:10000/mycontainer’) For more details, please type “AzCopy /?:Dest” or use verbose option /V.

1. How can I check if the api broke?
2. What “account information” am I missing?
