    --source -s                  [Required] : The directory where the files to be uploaded are

                                              authentication. The legacy "key" mode will attempt to
                                              query for an account key if no authentication

    Upload all files from local path directory to a container named "mycontainer".
        az storage blob upload-batch -d mycontainer -s <path-to-directory>


    Upload all files with the format 'cli-2018-xx-xx.txt' or 'cli-2019-xx-xx.txt' in local path
    directory.
        az storage blob upload-batch -d mycontainer -s <path-to-directory> --pattern
        cli-201[89]-??-??.txt


    Upload all files with the format 'cli-201x-xx-xx.txt' except cli-2018-xx-xx.txt' and
    'cli-2019-xx-xx.txt' in a container.

We are adding --overwrite in 2.39.0 without changing existing behavior, (for download overwrite by default, and for download-batch does not overwrite by default)

Was not able to reproduce it either with the same python version 3.8.9. Please try rerunning pip install azure-cli
