Replication with Redis causing error on sync

I’ve tried searching online and in this forum for anything related to these 3 errors that keep repeating when trying to do an initial sync with Redis. I can’t find anything at all so I must be doing something wrong or I have inherited a non-standard Redis situation. If anyone has any advice I would be grateful.

Redis version is 7.4.0
Dragonfly version is v1.24.0-7870f594660539f48894e37a8fd9d6a133fa21ff
build time: 2024-10-15 21:46:49

Error is

W20241029 15:34:22.697108 35485 rdb_load.cc:2600] Unrecognized RDB AUX field: 'aof-base'
E20241029 15:34:22.697160 35485 rdb_load.cc:1501] Unsupported rdb type 21

Thank you for reporting this. Can you please provide more information about your setup (i.e., OS and their versions, containerized environment or not)?

In the meantime, I noticed that Redis 7.4.0 does have a RDB file format change, which might cause this incompatibility. I will check with engineers as well.
