Best Regrades!

Deleted documents won’t have a body in the doc (only in oldDoc) so be careful about that.

HI @borrrden:

thanks for you reply. I already check it for oldDoc. below is my sf logic:

function sync(doc, oldDoc) {
if (isDelete()) {
channel(oldDoc.channelId);
return;
}

if sf detect the document is DELETED, then use oldDoc.channelId and return.
this has error?

thanks
