Description
Originally reported on GitHub: https://github.com/couchbase/sync_gateway/issues/5610
Attached unit test to reproduce this - seemingly, if a user's access to a document is revoked and they lose access to a role that doesn't exist (i.e. it's removed from their admin_roles without ever being created through PUT /db/_role/foo), replication can panic. Stack trace on release/3.0.3:
2022/07/07 10:43:35 Unexpected panic: runtime error: invalid memory address or nil pointer dereference - stopping process
