Usually when this happens it means that your sync function is rejecting
deletion (‘tombstone’) revisions.
Deletions are sort of a special case, because a typical deletion revision just
looks like {“id”:”xxx”, “_deleted”:true}, with no other properties. A common
mistake is to have your sync function require other properties — like “type” or
“owner” or whatever — and throw an exception if they’re not present. This will
unintentionally reject deletions.
In general the sync function will need to check for (doc._deleted === true) and
if so skip any checks for required properties. You do also probably want to
look at the oldDoc to validate that it’s legal for the user to delete this
document.
