silvpol opened a new issue #3955:
URL: https://github.com/apache/couchdb/issues/3955
## Description
In a partitioned DB using custom reduce function doesn't work, all queries
to that view fail with 500 error. Creating exact same view in non-partitioned
db works. Built in reduce funtions work fine though.
## Steps to Reproduce
1. Set up CouchDB cluster
2. Create partitioned and non-partitioned DBs
3. Apply the example view on both
4. Try to query in both databases
5. Swap custom reduce for _count built-in
6. Now works on both DBs
## Expected Behaviour
Custom reduce functions should work fine on partitioned DB or should be
documented non-working
## Your Environment
Docker Compose setup with three nodes using Docker Hub `couchdb:3` image
* CouchDB version used: 3.2.1
* Browser name and version: Postman 9.4.12
* Operating system and version: Docker container on MacOS 10.15.7
