Specify the URI of the calendar to be deleted

Error message

Specify the URI of the calendar to be deleted

What it means

InvalidArgumentException from occ dav:delete-subscription when the uri argument is present but empty after casting to string. Although declared REQUIRED, Symfony console accepts an empty string for required arguments in some invocation styles, so the command guards explicitly and refuses to query with an empty URI.

Solutions

1. Pass the exact subscription URI: list them first with occ dav:list-subscriptions <uid>
2. Validate that the uri variable is non-empty before invoking the command in scripts
3. Skip rows with blank URIs in batch imports and report them separately

Example fix

# before: empty uri argument
occ dav:delete-subscription jdoe ''
# after: list subscriptions, then pass the exact URI
occ dav:list-subscriptions jdoe
occ dav:delete-subscription jdoe company-holidays

#!/bin/bash
uid="$1"; uri="$2"
if [ -z "$uri" ]; then
  occ dav:list-subscriptions "$uid"  # show valid URIs
  echo 'pass a subscription URI' >&2; exit 1
fi
occ dav:delete-subscription "$uid" "$uri"

When it happens

Trigger: occ dav:delete-subscription <uid> '' or a wrapper forwarding an unset/empty URI variable; JSON/CSV-driven scripts where the uri column is blank for a row.

Common situations: Shell wrappers passing "$uri" when uri is unset; CSV rows with missing values; nested quoting that collapses the argument to an empty string.
