azure-cli: `Failed precondition` when trying to batch delete blobs

Describe the bug When running:

    az storage blob delete-batch \
        --account-name "$AZURE_ACCOUNT_NAME" \
        --account-key "$AZURE_ACCOUNT_KEY" \
        --source "$CONTAINER" \
        --if-unmodified-since "$DATE"

I get:

To Reproduce Run

    az storage blob delete-batch \
        --account-name "$AZURE_ACCOUNT_NAME" \
        --account-key "$AZURE_ACCOUNT_KEY" \
        --source "$CONTAINER" \
        --if-unmodified-since "$DATE"

Expected behavior The blobs to be deleted.

Environment summary Installed in a virtualenv through pip.

Happens on both a CentOS TeamCity agent and locally on Cygwin.

@williexu I’ll see if I can find an account to try it on, but is that seriously the expected response format, an array of nulls if it’s deleted something, plus a load of Failed precondition to the terminal with no blob names or anything if it fails to meet the date?

That output is so unusable for anything. 😂

@highbass I just successfully ran the following command:

az storage blob delete-batch --account-name wilxstoragebatch -s wilxcontainer --if-unmodified-since `date -u -d "10 minutes ago" '+%Y-%m-%dT%H:%MZ'` --debug

Have you tried doing a blob list after to see if any of your blobs were deleted (it’s possible that some failed while others succeeded)?. In addition, if you can, try this on a smaller container, which you can populate with a smaller number of blobs and run the command with --debug so we can see what is happening.

I can’t reproduce a problem with the delete-batch command.

Such messages are printed to stderr so they will not interfere with any parsing. This command in particular is a CLI convenience command, not the result of a single API call, so we have full control over the output format (which is sounds like needs some work).

@ElvenSpellmaker can you raise a separate issue for the messages displayed? On that note, Failed Precondition messages do seem like unnecessary bloat, I may change that to ‘debug’ output or remove them entirely.
