Cannot specify both 'users' and 'all_users=True'. Choose one

Error message

Cannot specify both 'users' and 'all_users=True'. Choose one approach.

What it means

Cross-field validator on the bulk user-update request: both an explicit 'users' list and all_users=True were supplied at once. These are mutually exclusive targeting modes; remove one before retrying.
