After running the following command:

Can you install storage-blob-preview extension with az extension add -n storage-blob-preview and try az storage blob upload --data? --data can take input string as blob content directly.

Thank you for your feedback. This has been routed to the support team for assistance.

az storage blob upload -c mycontainer --data "Foo Bar" --length 7 -n test.txt
