SyncFunc: oldDoc parameter is always null

[dangrieshaber]

Checking any value against the old document fails as the oldDoc parameter is always null.

Sync Gateway version

Couchbase Sync Gateway/3.2.0(514;release) CE

Operating system

Windows (all versions)

Expected behavior

oldDoc contains a reference to the changed document in its previous state

Actual behavior

oldDoc parameter is null

Steps to reproduce

1. Create Sync Function that checks the null-state of oldDoc parameter
2. Update a document relevant for sync
3. oldDoc value is null in SyncFunc

Getting the same behaviour when syncing down docs that need to compare the old doc to the new doc using the sync function. Has this received any attention as of yet? Is a fix on the way or an alternative version that I can use?

The sync function is only run when documents are updated. You mentioning syncing down documents, but the sync function is not populated. This functionality is not generally broken in Sync Gateway 3.2.0.

Can you provide database configuration and the recipe for how you are updating the documents?
