Got similar issue while trying Azure Sample first-serverless-app.
Here is the info of how i resolved by removing \ at front of $web.

Note: $web container was created automatically while enable static website. Never seen $root container anywhere.

//getting Invalid URI error while following tutorial as-is
az storage blob upload-batch -s . -d \$web --account-name firststgaccount01

//Remove "\" @destination param
az storage blob upload-batch -s . -d $web --account-name firststgaccount01
